# Need help #Brilliant Community

I have recently been solving some problems on polynomials an arbitrary example of which is

If p(x)= x^3+px^2+qx +10 has the roots a,b and c then what is the value of p+q?

Note-This is an arbitrary example and not a real question.

So, I have been facing problems in such questions and need your help.

How do I approach such questions? Any brilliant wiki or a website or a book for reference? Thank you in advance.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

• Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
• Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
• Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
