Sweet! I also have to ask, have you ever tried science bowl. I'm stuck between doing track, science bowl, or mathcounts . Plus I just found out that for the science and math competitions that my magnet school can't compete in them as a team I was like, " what the **!" Luckily, I heard my other school actually has a decent team. I guess I'll try it next year. Is it only 7th-8th grade. Geez, I have to many unanswered questions.

Yes! I attribute my recent change mostly to Brilliant Squared, though. Aside from that, @Anish Puthuraya's YouTube channel has been a great resource, along with Khan Academy and a Physics II for Dummies textbook. When I'm unfamiliar with an approach, Google is very helpful, and once I master a formula, I can apply it!

Oh yeah but also the thing about Brilliant Squared is that the problems are ranked way higher than they should be. I think it's mostly because the staff can choose the rating, even though in reality it gets pushed down a ton.

Oh yeah and #Finn is a pretty epic tag. :D

@Yan Yau Cheng I have a much simpler proof for problem #5.

Question Statement:

Given that \(p\) and \(p^2 + 8\) are both primes , what is the sum of all possible
values of \(p\)?

Solution:

We can see that if \(p \equiv 1\) or \(p \equiv 2 \pmod{3}\), then \(p^2\) will be congruent to \(1\) or \(4\) modulo \(3\), respectively (which is simply \(1^2\) and \(2^2\)). In both of these cases, by adding \(8\) which is \(\equiv -1 \pmod{3}\), the expression is \(\equiv 0 \pmod{3}\) and is thus never prime (it's divisible by \(3\)). For \(p \equiv 0 \pmod{3}\), the expression is congruent to \(0+8 \equiv 2 \pmod{3}\) which may or may not be prime. But because \(3\) is the only prime divisible by \(3\), we can just plug that in, which is \(3^2+8=17\) which is prime. Thus \(\boxed{3}\) is the only solution.

Recall that your problem had a wrong answer, and hence had an inflated rating. When we corrected it, the ratings were then pushed down. Given that it simply uses Newton formula, it's definitely not in level 5.

There is a possibility that the numbers are not accurate, given that we had to change the answer.

I see. But the numbers were unchanged, so I don't think that that would have done anything. Especially considering that the moment you changed the answer, the # of solvers went from 1 to 16. But Newton's Sums is still a Level 4 concept, especially in that application of it. I'd appreciate it if you gave it the correct rating. Thanks. :D

1) \(g(x) \) is a polynomial, otherwise I can define \( |g(3) | \) to be anything.
2) The degree of \(g(x) \) matters, otherwise we can take the square.
3) The leading coefficient of \( g(x) \) matters, otherwise we can just multiply by 2.

@Finn Hulse
–
The polynomial \( g(x) = (5(3)^5+3(3)^4-11(3)^3-2(3)^2+3(3)+5) ^2 \) will also satisfy your conditions as previously stated, namely that each of the roots of \( g(x) \) is the reciprocal of one of \( f(x) \) roots.

Note that currently, saying "the coefficient of \(x^5 \) is -5 is also not sufficient, since I could take \( g(x) = A(5(3)^5+3(3)^4-11(3)^3-2(3)^2+3(3)+5) ^2 \) for some suitable constant \(A\).

Note that you will also need the condition that "each of \( f(x) \) roots are the reciprocal of \( g(x) \) roots", otherwise, I can just take \( \alpha x - 1 \), where \( f( \alpha ) = 0 \).

The issue with some of your problems is that they are not correctly and clearly phrased. You have an idea of what it is in your head, but when written down, it could be interpreted in a multitude of ways. You need to take care of such 'edge cases' that I listed out above, instead of expecting others to deduce what you are thinking. They will not do so, and would instead just skip your problem.

I've made some changes which makes \( g(x) \) uniquely determined (up to sign). There are possibly better ways of expressing it that are not so clunky.

Log in to reply

@Anish Puthuraya's YouTube channel has been a great resource, along with Khan Academy and a Physics II for Dummies textbook. When I'm unfamiliar with an approach, Google is very helpful, and once I master a formula, I can apply it!

Yes! I attribute my recent change mostly to Brilliant Squared, though. Aside from that,Oh yeah but also the thing about Brilliant Squared is that the problems are ranked way higher than they should be. I think it's mostly because the staff can choose the rating, even though in reality it gets pushed down a ton.

Oh yeah and #Finn is a pretty epic tag. :D – Finn Hulse · 3 years, 1 month ago

@Yan Yau Cheng I have a much simpler proof for problem #5.

Question Statement:

Given that \(p\) and \(p^2 + 8\) are both primes , what is the sum of all possible values of \(p\)?

Solution:

We can see that if \(p \equiv 1\) or \(p \equiv 2 \pmod{3}\), then \(p^2\) will be congruent to \(1\) or \(4\) modulo \(3\), respectively (which is simply \(1^2\) and \(2^2\)). In both of these cases, by adding \(8\) which is \(\equiv -1 \pmod{3}\), the expression is \(\equiv 0 \pmod{3}\) and is thus never prime (it's divisible by \(3\)). For \(p \equiv 0 \pmod{3}\), the expression is congruent to \(0+8 \equiv 2 \pmod{3}\) which may or may not be prime. But because \(3\) is the only prime divisible by \(3\), we can just plug that in, which is \(3^2+8=17\) which is prime. Thus \(\boxed{3}\) is the only solution. – Finn Hulse · 3 years, 1 month ago

I see. But the numbers were unchanged, so I don't think that that would have done anything. Especially considering that the moment you changed the answer, the # of solvers went from 1 to 16. But Newton's Sums is still a Level 4 concept, especially in that application of it. I'd appreciate it if you gave it the correct rating. Thanks. :DLog in to reply

@Calvin Lin Have you seen this epic problem!? I think it's really cool and takes advantage of one of the coolest algebraic principles that I know! You'll enjoy it! :D – Finn Hulse · 3 years, 2 months ago

Log in to reply

1) \(g(x) \) is a polynomial, otherwise I can define \( |g(3) | \) to be anything.

2) The degree of \(g(x) \) matters, otherwise we can take the square.

3) The leading coefficient of \( g(x) \) matters, otherwise we can just multiply by 2. – Calvin Lin Staff · 3 years, 2 months ago

Log in to reply

– Finn Hulse · 3 years, 2 months ago

What do you mean the degree of \(g(x)\) matters?Log in to reply

Note that currently, saying "the coefficient of \(x^5 \) is -5 is also not sufficient, since I could take \( g(x) = A(5(3)^5+3(3)^4-11(3)^3-2(3)^2+3(3)+5) ^2 \) for some suitable constant \(A\).

Note that you will also need the condition that "each of \( f(x) \) roots are the reciprocal of \( g(x) \) roots", otherwise, I can just take \( \alpha x - 1 \), where \( f( \alpha ) = 0 \).

The issue with some of your problems is that they are not correctly and clearly phrased. You have an idea of what it is in your head, but when written down, it could be interpreted in a multitude of ways. You need to take care of such 'edge cases' that I listed out above, instead of expecting others to deduce what you are thinking. They will not do so, and would instead just skip your problem. – Calvin Lin Staff · 3 years, 2 months ago
