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

若要对表达式执行加法或减法运算，请重写该表达式，使其分母相同。求 x^{3}-2x^{2}-5x-3 与 \frac{x}{x} 的乘积。

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

由于\frac{\left(x^{3}-2x^{2}-5x-3\right)x}{x}和\frac{6}{x}具有相同的分母，可通过分子相加来求和。

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

完成 \left(x^{3}-2x^{2}-5x-3\right)x+6 中的乘法运算。
