Question

Please help u have to factor

Answer 1

Both terms have a $-m^2n$ in common, so we can pull it out. The factored form will be $-m^2n$ times whatever is left after pulling it out.

In the first term, we will have just 8 left since everything else in the term is factored out.

The second term has a $7m^4n^3$ left. Notice that both of these terms no longer have a negative sign since the negative was factored out.

The answer is $(-m^2n)(8+7m^4n^3)$
