Answer:
x^3 - 9x^2 +14x +24
Step-by-step explanation:
(x-4)(x^2 - 5x - 6)
First multiply x by everything in the second term
x (x^2 - 5x - 6) = x^3 -5x^2 -6x
Then multiply -4 by everything in the second term
-4 (x^2 - 5x - 6) = -4x^2 +20x +24
Then we add the results together.
I like to line them up vertically.
x^3 -5x^2 -6x
-4x^2 +20x +24
------------------------------
x^3 - 9x^2 +14x +24
