n=-18/4
n=-9/2
<span>X^2+x-2/1-x^2 ÷ 2x^2-6x-20/x^2-4x-5
(x + 2)(x - 1) (x - 5)(x + 1)
= ------------------- * ---------------------
(1 + x)(1- x) 2(x + 2)(x - 5)
</span> (x - 1)
= ----------
2(1- x)
- (1 - x)
= -------------
2(1 - x)
= -1/2
answer

Step-by-step explanation:
To simplify, you just condense all of the values with the same variable, based on the signs of those values.

6y + 8y + 5z - 3z
which can be simplified to
14y + 2z
which is the answer to your question.
