Factor polynomial $$ 5x^{3}+10x^{2}+3x+6 $$
Answer
$$ 5x^{3}+10x^{2}+3x+6 = ( 5x^{2}+3 )( x+2 ) $$
Explanation
To factor $ 5x^{3}+10x^{2}+3x+6 $ we can use factoring by grouping:
Group $ \color{blue}{ 5x^{3} }$ with $ \color{blue}{ 10x^{2} }$ and $ \color{red}{ 3x }$ with $ \color{red}{ 6 }$ then factor each group.
$$ \begin{aligned} 5x^{3}+10x^{2}+3x+6 = ( \color{blue}{ 5x^{3}+10x^{2} } ) + ( \color{red}{ 3x+6 }) &= \\ &= \color{blue}{ 5x^{2}( x+2 )} + \color{red}{ 3( x+2 ) } = \\ &= (5x^{2}+3)(x+2) \end{aligned} $$This page was created using
