Factor completely -5x^3 + 10x^2

-5x^2(x-2)

To factor completely -5x^3 + 10x^2, you can factor out the greatest common factor (GCF) from both terms. In this case, the GCF is 5x^2. So, we can rewrite the expression as follows:

-5x^3 + 10x^2 = 5x^2(-x + 2)

Therefore, the fully factored form of -5x^3 + 10x^2 is 5x^2(-x + 2).
