Question

In the following exercises, multiply the binomials. Use any method.
242. (y + 7)(y + 4)

Answer 1

the answer: y^2+11y+28

Answer 2

Hence the expression
`$(y+7)(y+4)=y^(2)+11 y+28$`

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.

`\begin{array}{r}y+7 \\\underline {* \quad y+28} \\4 y+28 \\\underline {y^(2)+7 y }\\y^(2)+11 y+28\end{array}`
