# How do you find the product -5w^2(8w^2x-11wx^2)+6x(9wx^4-4w-3x^2)?

$- 40 {w}^{4} x + 55 {w}^{3} {x}^{2} + 54 w {x}^{5} - 24 w x - 18 {x}^{3}$
$- 5 {w}^{2} \left(8 {w}^{2} x - 11 w {x}^{2}\right) + 6 x \left(9 w {x}^{4} - 4 w - 3 {x}^{2}\right)$
$= - 40 {w}^{4} x + 55 {w}^{3} {x}^{2} + 54 w {x}^{5} - 24 w x - 18 {x}^{3}$
