246. (q − 5)(q + 8)

Answer 1

Hence the expression
`$$(q-5)(q+8)=q^2+3q-40$$`

Explanation:

Explanation

• The given expression is (q-5)(q+8).
• We have to multiply the given expression.
• Multiply the (q-5) by 8 , multiply the (q-5) by q then add like terms.

`$$\frac{\begin{matrix}{} & {} & q & - & 5 \\ * & {} & q & + & 8 \\ \end{matrix}}`

_____________

`{\frac{\begin{matrix}{} & {} & 8q & - & 40 \\ {{q}^2} & - & 5q & {} & {} \\ \end{matrix}}{\begin{matrix}{{q}^2} & + & 3q & - & 40 \\ \end{matrix}}}$$`
