Question 268837
how is this!
--------------
(-3x^(2)-4x^(3)+x^(2)+4)/(x^(2)+x-1)

Since -3x^(2) and x^(2) are like terms, subtract x^(2) from -3x^(2) to get -2x^(2).
(-2x^(2)-4x^(3)+4)/(x^(2)+x-1)

Factor out the GCF of -2 from each term in the polynomial.
(-2(2x^(3))-2(x^(2))-2(-2))/(x^(2)+x-1)

Factor out the GCF of -2 from -4x^(3)-2x^(2)+4.
(-2(2x^(3)+x^(2)-2))/(x^(2)+x-1)

Move the -1 to the front of the fraction.
-(2(2x^(3)+x^(2)-2))/(x^(2)+x-1)
