Question #2 What is the difference?​

Answer 1

B
`(b-10)/(b-1)`

Explanation:

In order to get the same denominator, we need to multiply the second fraction by (b+2) in the numerator and denominator.

We will end up in something like this :
`(b^(2) - 2b - 8 -6(b+2) )/((b-1)(b+2))`

I just timed the second fraction by b+ 2 and then i added them together.

Therefore, we will get
`(b^(2) - 8b - 20)/((b-1)(b-2))`

now factoring the numerator we will end like this

`((b-10)(b+2))/((b-1)(b+2))`

we will then end up with the answer.

Hope this helps.
