Thanks for using the magic word please.
Given;
(1) %283x%5E3%29%2A%28-4x%5E%28-4%29%29
First multiply the coefficients 3 and -4 to get
(2) -12%2A%28x%5E3%29%2A%28x%5E%28-4%29%29
Now multiply the two powers, x%5E3 and x%5E%28-4%29, together. Since the two powers have the same base, x, we merely add the exponents to get
(3) -12%2A%28x%5E%283-4%29%29 or
(4) -12%2A%28x%5E%28-1%29%29
Answer: -12%2Ax%5E%28-1%29
