Verified Answer :

The fully factored form of this expression would be:

(B+8)(B+4).

Answer:

\((b+4)(b+8)\)

Step-by-step explanation:

The given quadratic trinomial is

\(b^2+12b+32\)

We split the middle term to obtain;

\(b^2+8b+4b+32\)

We factor to get;

\(b(b+8)+4(b+8)\)

We factor further to get;

\((b+4)(b+8)\)
