Answer:

  20x^4 -24x^3 +20x^2

Step-by-step explanation:

Usually, "simplification" means the parentheses are removed, like terms are combined, and terms are written in order of decreasing degree.

-4x^2(6x-5x^2-5)

  = (-4x^2)(6x) +(-4x^2)(-5x^2) +(-4x^2)(-5) . . . . use the distributive property

  = -24x^3 +20x^4 +20x^2

  = 20x^4 -24x^3 +20x^2
