We are given the following operation of polynomials:
First, we will apply the distributive property on the parenthesis. This means that we will change the sign of the terms inside each of the parenthesis that have a minus sign on the left side, like this:
Now, we associate like terms. This means the terms that have the same variables elevated at the same exponents, like this:
Now, we add the coefficients of the like terms:
Since we can't simplify any further this is the final answer.
