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

Da biste izvršili zbrajanje ili oduzimanje izraza, rastavite ih kako bi im nazivnici bili isti. Pomnožite 2 i \frac{\left(2x-1\right)^{2}}{\left(2x-1\right)^{2}}.

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

Pošto \frac{-2}{\left(2x-1\right)^{2}} i \frac{2\left(2x-1\right)^{2}}{\left(2x-1\right)^{2}} imaju isti imenilac, oduzmite ih tako što ćete oduzeti njihove brojioce.

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

Izvršite množenja u -2-2\left(2x-1\right)^{2}.

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

Kombinirajte slične izraze u -2-8x^{2}+8x-2.

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

Proširite \left(2x-1\right)^{2}.
