Question 1034129: x^2-2x-8
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! (x-4) * (x+2)
x-4 = 0
solve for x to get x = 4
s+2 = 0
solve for x to get x = -2
(x-4) * (x+2) = x^2 + 2x - 4x - 8
combine like terms to get (x-4) * (x+2) = x^2 - 2x - 8.
since that's your original equation, the factors look good.
your solutions are x = 4 or x = -2.
