Answer 2

Answer:

$-2b^2+17b-15$ is your answer. I hope this helps! Let me know if I got anything wrong or if you need any help.

Step-by-step explanation:

$(b^2+13b-9)-(6-4b+3b^2)$

Expland the brackets.

$b^2+13b-9-6+4b-3b^2$

Add like terms.

$-2b^2 + 13b - 9-6+4b$

$-2b^2+17b-9-6$

$-2b^2+17b-15$

$-2b^2+17b-15$ is your answer. I hope this helps! Let me know if I got anything wrong or if you need any help.
