Question

Factor by grouping m^2 + 6m - 12m - 72

Answer 1

Equation:

$m^2+6m-12m-72$

To factor by grouping, we have to evaluate the common factors between each term.

We can see that the second and third terms have an m as a common term. Thus, we can group them and simplify them as follows:

$=m^2+(6m-12m)-72$$=m^2-12m-72$

Now, we have three terms that have different factors and we cannot further simplify.

Answer:

$=m^2-12m-72$
