Question

x_2÷x3+5x2+9x+3
$x - 2 \div x3 + 5x2 + 9x + 3$

Answer 1

$x - 2 \div {x}^{3} + 5 {x}^{2} + 9x + 3 \\ x - \frac{2}{ {x}^{3} } + 5 {x}^{2} + 9x + 3 \\ 10x+ - \frac{2}{ {x}^{3} } + 5 {x}^{2} + 3 \\ \frac{10 {x}^{4} - 2 + 2 {x}^{5} + 3 {x}^{3} }{ {x}^{3} } \\ \frac{5 {x}^{5} + 10 {x}^{4} + 3 {x}^{3} - 2 }{ {x}^{3} }$
