I can flip the denominator of the whole fraction to multiply and factorize the y out but I can't seem to figure out a way to get past this:

$\displaystyle \frac{2x^2y-xy+4x^3-2x^3-2x-2x^2+1}{(2x^2-1)(x)}$

The answer to the question comes out as $\displaystyle \frac{y+2x-1}{x}$

So I'm not sure how the first equation comes out as that ^
