# How do you simplify (42x^4 + 48x^3 + 48x^2)/(6x^3)?

$\textcolor{w h i t e}{\times} \frac{7 {x}^{2} + 8 x + 8}{x}$
$\textcolor{w h i t e}{\times} \frac{42 {x}^{4} + 48 {x}^{3} + 48 {x}^{2}}{6 {x}^{3}} = \textcolor{red}{\frac{6 {x}^{2}}{6 {x}^{2}}} \times \frac{7 {x}^{2} + 8 x + 8}{x}$
$\textcolor{w h i t e}{\times \times \times \times \times \times \times x} = \frac{7 {x}^{2} + 8 x + 8}{x}$
