x squared -1 over 1-x , I'm suppose to simplify but I dont see how, please help me understand

Question

anonymous · Answer

$$x^2-1/1-x$$ I'm going to assume this is the equation you are asking about.  So what you do is you factor the top polynomial.  $$x^2-1=(x+1)(x-1)$$ Thus, you have (x+1)(x−1)/(1-x)

anonymous · Answer

$$\LARGE x^2-\frac{1}{1-x}$$ this ? or like post above :)

anonymous · Answer

But you can rewrite x-1 as -(1-x) so you have...

anonymous · Answer

i did the first one you posted

anonymous · Answer

-(x+1)(1-x)/1−x=-(x+1)
so your final answer is -x-1

|dw:1334897105038:dw| is what i did

anonymous · Answer

Im sorry i stil dont see how you got -x-1 from that

anonymous · Answer

Okay so $$(x^2-1)/(1-x)=(x+1)(x-1)/(1-x)=-(x+1)(1-x)/(1-x)$$

anonymous · Answer

You cancel out (1-x) then you are left with -(x+1)=-x-1
