Answer:

B $\frac{b-10}{b-1}$

Step-by-step 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 : $\frac{b^{2} - 2b - 8 -6(b+2) }{(b-1)(b+2)}$

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

Therefore, we will get $\frac{b^{2} - 8b - 20}{(b-1)(b-2)}$

now factoring the numerator we will end like this

$\frac{(b-10)(b+2)}{(b-1)(b+2)}$

we will then end up with the answer.

Hope this helps.

The answer is -60. this is because the signs implemented in front of numbers give it a sort pattern .

when there are two additions the last number after the positive sign will give a positive number 1 greater than the initial number for example + 5 + 6. Answer afterward will be + 7 and for negative sign eg: - 7 - 8 in the question will give the answer -8 the same number after a negative (-) sign .
Hope this helps
