Answer:

<em>The answer is:  x^3-9x^2+14x+24</em>

Step-by-step explanation:

The given expression is:  (x-4)(x^2-5x-6)

For getting the product, <u>we need to distribute (x-4) with each term in the second parenthesis</u>. So.....

(x-4)(x^2-5x-6)\\ \\ =x^2(x-4)-5x(x-4)-6(x-4)\\ \\ =x^3-4x^2-5x^2+20x-6x+24 \ [using\ distribution\ rule]\\ \\ =x^3-9x^2+14x+24\ [combining\ like\ terms]

So, the answer is:  x^3-9x^2+14x+24
