Question
Factor polynomial $$ 6w^{3}+15w^{2}-14w-35 $$
Answer
$$ 6w^{3}+15w^{2}-14w-35 = ( 3w^{2}-7 )( 2w+5 ) $$
Explanation
To factor $ 6w^{3}+15w^{2}-14w-35 $ we can use factoring by grouping:
Group $ \color{blue}{ 6x^{3} }$ with $ \color{blue}{ 15x^{2} }$ and $ \color{red}{ -14x }$ with $ \color{red}{ -35 }$ then factor each group.
$$ \begin{aligned} 6w^{3}+15w^{2}-14w-35 = ( \color{blue}{ 6x^{3}+15x^{2} } ) + ( \color{red}{ -14x-35 }) &= \\ &= \color{blue}{ 3x^{2}( 2x+5 )} + \color{red}{ -7( 2x+5 ) } = \\ &= (3x^{2}-7)(2x+5) \end{aligned} $$This page was created using
