#### Explanation:

$\textcolor{w h i t e}{a a a a a a a a a a a a a a a}$$9 {x}^{2} + 5$
$\textcolor{w h i t e}{a a a a a a a a a a a a a a a}$$x - 1$
$\textcolor{w h i t e}{a a a a a a a a a a a a a a a}$$- - -$
$\textcolor{w h i t e}{a a a a a a a a a a a a a a a}$$9 {x}^{3} + 5 x$
$\textcolor{w h i t e}{a a a a a a a a a a a a a a a a}$$- 9 {x}^{2} - 5$
$\textcolor{w h i t e}{a a a a a a a a a a a a a a a a}$$- - - - -$
$\textcolor{w h i t e}{a a a a a a a a a a a a a a a}$$9 {x}^{3} - 9 {x}^{2} + 5 x - 5$
