Solve (10x^3+30x-20)÷(-5x+5)

Question

2x^2-2x+4
-2x^2-2x-4
-2x^2+2x+4
2x^2+2x-4

Answer 1

you have

5(2x^3+6x-4) / -5(x-5)
= -(2x^3+6x-4)/(x-5)
a little synthetic division shows that it does not divide evenly. I suspect a typo.

However, it is clear that only B or C could work, even after the typos is fixed.

Answer 2

Youre right its supposed to be
(-10x^3+30x-20)÷(-5x+5)

Answer 3

so, now it's down to A or D.
Do the math...
