Answer

$11x^3y^2-8x^2y-6x^2-6x+6$

Work Step by Step

Subtract each term to obtain: $=6x^3y^2-4x^2y-6x-(-5x^3y^2)-4x^2y-6x^2-(-6) \\=6x^3y^2-4x^2y-6x+5x^3y^2-4x^2y-6x^2+6$ Combine like terms to obtain: $=(6x^3y^2+5x^3y^2)+(-4x^2y-4x^2y)-6x^2-6x+6 \\=11x^3y^2+(-8x^2y)-6x^2-6x+6 \\=11x^3y^2-8x^2y-6x^2-6x+6$
