\frac{-2}{\left(2x-1\right)^{2}}-\frac{2\left(2x-1\right)^{2}}{\left(2x-1\right)^{2}}

Para sumar o restar expresiones, expándalas para que sus denominadores sean iguales. Multiplica 2 por \frac{\left(2x-1\right)^{2}}{\left(2x-1\right)^{2}}.

\frac{-2-2\left(2x-1\right)^{2}}{\left(2x-1\right)^{2}}

Como \frac{-2}{\left(2x-1\right)^{2}} y \frac{2\left(2x-1\right)^{2}}{\left(2x-1\right)^{2}} tienen el mismo denominador, reste sus numeradores para restarlos.

\frac{-2-8x^{2}+8x-2}{\left(2x-1\right)^{2}}

Haga las multiplicaciones en -2-2\left(2x-1\right)^{2}.

\frac{-4-8x^{2}+8x}{\left(2x-1\right)^{2}}

Combine los términos semejantes en -2-8x^{2}+8x-2.

\frac{-4-8x^{2}+8x}{4x^{2}-4x+1}

Expande \left(2x-1\right)^{2}.
