Going through the problems I came across: How many roots does the following equation have? |x^2 - 11| = |x-8|

After initially figuring out the answer, I came up with 4. It said I was wrong, there were 2?

I spent the next 3 hours trying to try different ways and establish how they came out with the answer 2... I still can't, I'm sure that the answer is 4!

Am I completely missing something?

TopNewestI can't see this 'dot dot dot' menu? I have come across a couple of errors and not been able to report them!

If you're referring to a community problem, it is located at the bottom just next to the number of solvers

If you are referring to the practice section, it is stated as "report problem" at the bottom

Thanks for that, I've reported it and it has now been rectified.

If you spot any errors with a problem, you can “report” it by selecting the “dot dot dot” menu in the lower right corner. You will get a more timely response that way.

Link to the question? Wolfram Alpha also gives the same.
