Factor polynomial $$ 4x^{4}y^{7}z^{3}+6x^{5}y^{5}z^{5}-8x^{3}y^{6}z^{4} $$
Answer
$$ 4x^{4}y^{7}z^{3}+6x^{5}y^{5}z^{5}-8x^{3}y^{6}z^{4} = 2x^{3}y^{5}z^{3}(2xy^{2}+3x^{2}z^{2}-4yz) $$
Explanation
Factor out common factor $ \color{blue}{ 2x^3y^5z^3 } $:
$$ 4x^4y^7z^3+6x^5y^5z^5-8x^3y^6z^4 = 2x^3y^5z^3 ( 2xy^2+3x^2z^2-4yz ) $$
