x^2=x+20 I'm wondering what the answer to this problem is.

THIS ISN't A HOMEWORK PROBLEM! Geeze.

How would some of you go about solving this?

edit: What would this kindof problem be called anyways?

Problems that can be expressed as AX^2 + BX + C = 0, where A, B, and C are constants are quadratic problems that can be solved using the quadratic formula. Or by factoring as ColonelWilks adeptly demonstrated.

In your example, A = 1, B = -1, and C = -20.
