Factor polynomial $$ 8a^{2}-20ab-12b^{2} $$
Answer
$$ 8a^{2}-20ab-12b^{2} = 4(a-3b)(2a+b) $$
Explanation
Step 1 :
Factor out common factor $ \color{blue}{ 4 } $:
$$ 8a^2-20ab-12b^2 = 4 ( 2a^2-5ab-3b^2 ) $$Step 2 :
$ 2a^2-5ab-3b^2 $ can be written as
$$ 2a^2-5ab-3b^2 = \left( a-3b \right) \left( 2a+b \right)$$The explanation for this step cannot be generated.
