Question

I need your help once again, Brian

Answer 1

`3b^2+2b-8`

Explanation:

Again, we can use FOIL to expand this equation:

First:
`3b(b)=3b^2`

Outer:
`3b(2)=6b`

Inner:
`-4(b)=-4b`

Last:
`-4(2)=-8`

We can combine the b terms to get
`2b`, and we have our answer as
`3b^2+2b-8`

Answer 2

3b^2+2b-8

Explanation:

(3b-4)(b+2)

FOIL

first:3b*b = 3b^2

outer:2*3b = 6b

inner: -4b

Last: -4*2 = -8

Add together

3b^2 +6b-4b-8

Combine like terms

3b^2+2b-8
