MathBot Answer:
Evaluated
\(\displaystyle -\left( 5 {x}^{2} \cdot \left(-{x}^{2} - 3 x\right) \right) = - 5 x^{2} \left(- x^{2} - 3 x\right) \)
Expanded
\[-\left( 5 {x}^{2} \cdot \left(-{x}^{2} - 3 x\right) \right) = 5 x^{4} + 15 x^{3}\]
Factored
\[-\left( 5 {x}^{2} \cdot \left(-{x}^{2} - 3 x\right) \right) = 5 x^{3} \left(x + 3\right)\]
