\frac{\frac{1}{8}\left(2x-1\right)\left(-4x^{2}-2x-1\right)}{\frac{1}{2}\left(2x-1\right)}
Factor the expressions that are not already factored.
\frac{\frac{1}{8}\left(-4x^{2}-2x-1\right)}{\frac{1}{2}}
Cancel out 2x-1 in both numerator and denominator.
\frac{-\frac{1}{2}x^{2}-\frac{1}{4}x-\frac{1}{8}}{\frac{1}{2}}
Expand the expression.
\left(-\frac{1}{2}x^{2}-\frac{1}{4}x-\frac{1}{8}\right)\times 2
Divide -\frac{1}{2}x^{2}-\frac{1}{4}x-\frac{1}{8} by \frac{1}{2} by multiplying -\frac{1}{2}x^{2}-\frac{1}{4}x-\frac{1}{8} by the reciprocal of \frac{1}{2}.
-x^{2}-\frac{1}{2}x-\frac{1}{4}
Use the distributive property to multiply -\frac{1}{2}x^{2}-\frac{1}{4}x-\frac{1}{8} by 2.
