Choose the correct simplification of the expression - 4x2 (6x - 5x2 - 5).

20x4 + 24x3 + 20x2

-9x4 + 2x3 - 9x2

20x4 - 24x3 + 20x2

-20x4 + 24x3 - 20x2

If you would like to solve - 4x^2 * (6x - 5x^2 - 5), you can do this using the following steps:

-4x^2 * (6x - 5x^2 - 5) = - 4x^2 * 6x + 4x^2 * 5x^2 + 4x^2 * 5 = - 24x^3 + 20x^4 + 20x^2 = 20x^4 - 24x^3 + 20x^2

The correct result would be 20x^4 - 24x^3 + 20x^2.
