need help with this problem? x exponent is 2 -x-56=0?

Question

x2 but the the 2 is small like this x³ but instead it a 2 .

Answer 1

This can be factored as follows:

x^2 - x - 56 = 0.
(x + 7)(x - 8) = 0.
x = -7 or 8.

Answer 2

Factor out the expression:
x^2-x-56=0
(x+7)(x-8)=0
solve for x
x+7 =0 or x-8=0
x=-7 or x=8

Answer 3

If you ment:

x² - x - 56 = 0

then:

(x-8) (x+7) = 0

x = 8 OR x = -7

and you are done.
To check your work, use FOIL method on (x-8) (x+7) to see if you get:
x² - x - 56
