You can put this solution on YOUR website! In this case, we will take each component in the first parenthesis and multiply it by each term in the second parenthesis. We will then combine like terms to determine its simplest form.
.
When we multiply terms with exponents, remember multiply the coefficients, but add their exponents. Since we have no coefficients (1 is implicit), we will only worry about the exponents.
.
Notice:
1. is the same as to say , so cancels with
2. cancels with
So, our final expression is:
