Differentiation

$\frac{9}{2} x^{7 / 2}-14 x^{5 / 2}+20 x^{3 / 2}-\frac{15}{2} x^{1 / 2}+2 x-3$

$\frac{9}{2} x^{7 / 2}-7 x^{5 / 2}+5 x^{3 / 2}-\frac{3}{2} x^{1 / 2}+2 x-3$

$9 x^{7 / 2}-14 x^{5 / 2}+20 x^{3 / 2}-15 x^{1 / 2}+2 x-3$

$\frac{9}{2} x^{7 / 2}-\frac{7}{2} x^{5 / 2}+\frac{5}{2} x^{3 / 2}-\frac{15}{2} x^{1 / 2}+2 x-3$
