Question

m ^ 2 * n ^ 2 - 49.

Answer 1

$\begin{gathered} \text{Given} \\ m^2\mleft(n^2-49\mright) \end{gathered}$

By distributive property, we "distribute" m² by multiplying it to each of the terms in side the binomial which will result to

$\begin{gathered} m^2(n^2-49)=m^2(n^2)+m^2(-49) \\ \Rightarrow m^2n^2-49m^2\text{ (final answer)} \end{gathered}$
