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