Question
Factor polynomial $$ 12ky^{2}+8ky-20k $$
Answer
$$ 12ky^{2}+8ky-20k = 4k(x-1)(3x+5) $$
Explanation
Step 1 :
Factor out common factor $ \color{blue}{ 4k } $:
$$ 12ky^2+8ky-20k = 4k ( 3y^2+2y-5 ) $$Step 2 :
$$ 3x^{2}+2x-5 = ( x - 1 )( 3x + 5 ) $$Click here to generate an explanation on how to factor $ 3x^{2}+2x-5 $.
