Question 119091: -x+xsquared=56 i've tired to solve it but i got confused because of the x's.
please help me solve the equation by factoring. Answer by tutorcecilia(2152) (Show Source):
You can put this solution on YOUR website! -x+xsquared=56 =56 =0 [subtract 56 from both sides; set the equation equal to zero]
(x-8)(x+7)=0 [factor]
x-8=0 [set each factor equal to zero and solve for the x-value]
x=8
and
x+7=0
x=-7
