Question 149857: I know (think) I did this right but does seem right.

6x^2+17x-40 + 3 - 5x
___________ ___ ______
x^2+x-20 x-4 x+5

This is what i did...
6x^2+17x-40 +3 -5x
___________ ____ _____
(x-4)(x+5) x-4 x+5

6x^2+17x-40 + 3(x+5) - 5x(x-4)
_____________________________________
(x-4)(x+5)

6x^2+17x-40 +3x+15-5x^2+20x = (6x^2-5x^2)+(17x+3x+20x)+(-40+15)= x^2+40x-25
x^2+40x-25
__________
(x-4)(x+5)
