-2x^3 - 4x^2 + 4x
-2x^3 = -2x(x^2)
-4x^2 = -2x(2x)
4x = -2x(-2)
so GCF= -2x
-2x3 - 4x2 + 4x = -2x(x^2 + 2x - 2)
answer is B. -2x(x^2 + 2x - 2)
For the equation -2x³ - 4x² + 4x
The common factor for the coefficients -2, -4 and 4 is -2, since all of them are divisible by -2.
The common factor for the variables x³, x² and x is x, since all of them are divisible by x.
Then, the GCF would be -2x. We use this to simplify the equation:
-2x(x² + 2x -2)
-2x3 - 4x2 + 4x
