SOLUTION:
Step 1:
In this question, we are meant to simplify the following:
[tex]-w^2(\text{ w- 15)}[/tex]Step 2:
The details of the solution are as follows:
[tex]-w^2(w-15)=-w^3+15w^2[/tex]Simplification:
[tex]\begin{gathered} -w^2Xw=-w^3 \\ -w^2X-15=15w^2 \\ Hence,\text{ we have that:} \\ -w^2(w-15)=-w^3+15w^2 \end{gathered}[/tex]
