Question

7X - 1/2 X la2 - 3X - 5/x la 2 - 9 + 9X - 3/2X la 3 - 18 X

Answer 1

$- 5x - \frac{1}{2} x {}^{2} - \frac{25}{x {}^{2} } - 9 - \frac{3}{2} x {}^{3} \\ \frac{ - 10x {}^{3 } - x {}^{4 } - 50 - 18x {}^{2} - 3x {5}^{2} }{2x {}^{2} }$
18x^2-3x^5
$\frac{ - 3x {}^{5} - x {}^{4} - 10x {}^{3} - 18x {}^{2} - 50 }{2x {}^{2} }$
