Answer 1

To factor the polynomial 4x^3 + 8x^2 - 96x, we first look for common factors in each term:

The common factor here is 4x, so we factor that out first:

4x(x^2 + 2x - 24)

Now, we need to factor the quadratic equation inside the parentheses. To do that, we look for two numbers that multiply to -24 (since it's the product of the last term) and add up to 2 (since it's the coefficient of the middle term):

The numbers that satisfy this are 6 and -4, since 6 * -4 = -24 and 6 + (-4) = 2.

So, we factor the quadratic part as:

x^2 + 2x - 24 = (x - 4)(x + 6)

Putting it all back together with the factored out 4x, we get:

4x(x - 4)(x + 6)

The correct answer is 4x(x - 4)(x + 6).
