# How do you multiply (4s^3+6s+1)(-2s)?

Expand. $- 8 {s}^{4} - 12 {s}^{2} - 2 s$
$\left[\left(4 \cdot {s}^{3}\right) \cdot \left(- 2 \cdot s\right) + \left(6 \cdot s\right) \cdot \left(- 2 \cdot s\right) + \left(- 2 \cdot s\right)\right]$
$\left(- 8 {s}^{4}\right) + \left(- 12 \cdot {s}^{2}\right) - \left(2 \cdot s\right)$
