Thanks @bohotness

Answer 3

Im still kind of confused on how I would combine them if they are not like terms. Like could I multiply x by y?

Answer 4

In this case, you have to take everything step-by-step.
So you'll multiply your first term "X" to the other parenthesis. You multiply it to every item in the second parenthesis. So you'll have (x^2+3)(x-4) = x^3-4x
Now, you'll multiply your second term "3" to the second parenthesis.
So: (x^2+3)(x-4)=x^3-4x^2+3x-12 is your final answer.

Hope that helps!
