Question

In the following exercises, multiply the binomials. Use any method.
252. (3r − 8)(11r + 1)

Answer 1

Hence the expression
`$$(3r-8)(11r+1)=33r^2-85r-8$$`.

Explanation:

Explanation

• The given expression is (3 r-8)(11 r+1).
• We have to multiply the given expression.
• Multiply the (3 r-8) by 1 , multiply the (3 r-8) by 11r then add like terms.

`$$\frac{\begin{matrix}{} & {} & 3r & - & 8 \\ * & {} & 11r & + & 1 \\ \end{matrix}}`

___________

`{\frac{\begin{matrix}{} & {} & 3r & - & 8 \\ 33{{r}^2} & - & 88r & {} & {} \\ \end{matrix}}{\begin{matrix}33{{r}^2} & - & 85r & - & 8 \\ \end{matrix}}}$$`
