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

若要對運算式相加或相減，請先通分使其分母相同。 2 乘上 \frac{\left(2x-1\right)^{2}}{\left(2x-1\right)^{2}}。

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

因為 \frac{-2}{\left(2x-1\right)^{2}} 和 \frac{2\left(2x-1\right)^{2}}{\left(2x-1\right)^{2}} 的分母相同，所以將分子相減即可相減這兩個值。

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

計算 -2-2\left(2x-1\right)^{2} 的乘法。

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

合併 -2-8x^{2}+8x-2 中的同類項。

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