Answer:

$-11b^2+8b-4$

Step-by-step explanation:

We can substitute in our expressions for P and Q to get

$P=-4b^2+6b-9\\Q=7b^2-2b-5\\\\(-4b^2+6b-9)-(7b^2-2b-5)$

Next, we need to distribute the negative to the values within the parenthesis. Then we can combine like terms in order to get our answer

$(-4b^2+6b-9)-(7b^2-2b-5)\\\\-4b^2+6b-9-7b^2+2b+5\\\\-11b^2+8b-4$
