Question

Answer 1

Answer:

$-b^2-13b+15$

Explanation:

Here, we want to perform the indicated operation

What we have to do here is to bring like terms together

We start by opening up the brackets

We have that as follows:

$\begin{gathered} b^2-13b+10-2b^2+5 \\ b^2-2b^2-13b+10+5 \\ -b^2-13b+15 \end{gathered}$
