Answer 2

`-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.

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.
