Question

Which expression is equivalent to 6m + (m – 2)(m + 7) + 3?

Answer 1

`m^2+11m-11` is the required equivalent expression.

Explanation:

We have been given the expression
`6m+(m-2)(m+7)+3`

We have to solve the given expression:

`6m+m^2+7m-2m-14+3`

After simplifying by combining the like terms

like terms means the terms with same degree in the above expression:

`m^2+11m-11`

Hence,
`m^2+11m-11` is the required expression.

Answer 2

6m + (m-2)(m+7) + 3 =
6m + m^2 + 7m - 2m - 14 + 3 =
m^2 + 11m - 11 <==
