Ответ:
[tex] \frac{5 {x}^{3} + 6 {x}^{2} - 6x + 3 }{ {x}^{2} } [/tex]
Объяснение:
[tex]5x - \frac{10}{2x} + 3 \div {x}^{2} - \frac{4}{4x} + 6 \\ 5x - \frac{5}{x} + \frac{3}{ {x}^{2} } - \frac{1}{x} + 6 \\ \frac{ {5x}^{3} - 5x + 3 - x + {6x}^{2} }{ {x}^{2} } \\ \frac{ {5x}^{3} - 6x + 3 + {6x}^{2} }{ {x}^{2} } \\ \frac{ {5x}^{3} + {6x}^{2} - 6x + 3 }{ {x}^{2} } [/tex]
