#### Explanation:

To multiply these two terms you multiply each individual term in the left parenthesis by each individual term in the right parenthesis.

$\left(\textcolor{red}{x} + \textcolor{red}{3}\right) \left(\textcolor{b l u e}{y} - \textcolor{b l u e}{4}\right)$ becomes:

$\left(\textcolor{red}{x} \times \textcolor{b l u e}{y}\right) - \left(\textcolor{red}{x} \times \textcolor{b l u e}{4}\right) + \left(\textcolor{red}{3} \times \textcolor{b l u e}{y}\right) - \left(\textcolor{red}{3} \times \textcolor{b l u e}{4}\right)$

$x y - 4 x + 3 y - 12$
