2.)Solve the equation x^2=x+56 by factoring.
Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
4x+5y=8
5y=-4x+8
y=-4x/5+8/5
(graph 300x200 pixels, x from -6 to 5, y from -10 to 10, -4x/5 +8/5).
------------------------------------------------------
x^2=x+56
x^2-x-56=0
(x-8)(x+7)=0
x-8=0 ans.
x+7=0
x=-7 ans.
