It can go into 136 4 times. Just do 136 divided by 34. It's even enough to go into it.
(12x^3-4x^2+8x)/(-2x) The greatest common factor of the numerator and denominator is -2x so upon division by GCF of both numerator and denominator you have:
-6x^2+2x-4 and we can now also factor out -2
-2(3x^2-x+2)
What they said was correct!!
