7X+2=5X+12 how do i show my work for this??

Subtract 2 from each side=7X+2-2=5X+12-2

simplify=7X=5X+10

subtract 5x=7X-5X=5X+10-5X

simplify=2x=10

divide both sides by 2=2x/2=10/2

simplify=x=5

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
