Your best friend was absent the day this lesson was taught. Which of the following summarizes how to multiply a monomial by a polynomial?

• The monomial needs to be multiplied by each term of the polynomial. When you multiply two terms, add the coefficients and for variables that are the same, multiply the exponents. Then, combine any like terms to find your final answer.

• The monomial needs to be multiplied by each term of the polynomial. When you multiply two terms, add the coefficients and keep the variables and exponents the same. Then, combine any like terms to find your final answer.
