Step-by-step explanation:
- The given expression is (y+7)(y+4).
- We have to multiply the given expression.
- Multiply the (y+7) by 4 , multiply the (y+7) by y then add like terms.
[tex]\begin{array}{r}y+7 \\\underline {\times \quad y+28} \\4 y+28 \\\underline {y^{2}+7 y }\\y^{2}+11 y+28\end{array}[/tex]
