\frac{\left(x^{3}-2x^{2}-5x-3\right)x}{x}+\frac{6}{x}

若要對運算式相加或相減，請先通分使其分母相同。 x^{3}-2x^{2}-5x-3 乘上 \frac{x}{x}。

\frac{\left(x^{3}-2x^{2}-5x-3\right)x+6}{x}

因為 \frac{\left(x^{3}-2x^{2}-5x-3\right)x}{x} 和 \frac{6}{x} 的分母相同，所以將分子相加即可相加這兩個值。

\frac{x^{4}-2x^{3}-5x^{2}-3x+6}{x}

計算 \left(x^{3}-2x^{2}-5x-3\right)x+6 的乘法。
