If the directions is to simplify the following polynomials, then explain what I perhaps did wrong or explain what the answer should be.
$3{x}^{2}\left(5x\right)\left(-\frac{2}{3}{x}^{3}\right)\to 15{x}^{3}-2{x}^{5}$

To solve the polynomial $3{x}^{2}\left(5x\right)\left(-\frac{2}{3}{x}^{3}\right)$
Apply the rule: $a\left(-b\right)=-ab$

$=-3{x}^{6}\cdot 5\cdot \frac{2}{3}$
$=-10{x}^{6}$
Therefore, $3\left({x}^{2}\right)\left(5x\right)\left(-\frac{2}{3}{x}^{3}\right)=-10{x}^{6}$
