Which expression is equivalent to 6m + (m - 2)(m + 7) + 3?
m²+ 11m - 11
m²+ 6m - 11
7m²+ 47m - 11
7m²+ 47m - 14

Solution:

The given expression is 6m + (m - 2)(m + 7) + 3

Let us factorise

= 6m + m² + 7m - 2m - 14 + 3

By further simplification

= m² + 11m - 11

Therefore, the expression m² + 11m - 11 is equivalent.

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

Summary:

The expression m² + 11m - 11 is equivalent to 6m + (m - 2)(m + 7) + 3.
