Question

Can Someone walk me through this? I think I've done it right but would like someone to check it and let me know if I'm wrong...
Simplify the Sum:
b^2+4b-32/b^2+13b+40 +(PLUS)+ b^2+b-20/b^2+3b-28

Answer 1

First I factored so it was then (x+8)(x-4)/(x+8)(x+5) +PLUS+ (x+5)(x-4)/(x+7)(x-4)

Answer 2

What did you get as your answer?

Answer 3

2b^2+13b-3/(b+5)(b+7)

Answer 4

hold on let me check

Answer 5

Okayy, thankyou!

Answer 7

I'm getting \[\Large \frac{2b^2+13b-3}{(b+7)(b+5)}\] as well. Nice job
