Quizplus · Accepted Answer

Subtracting the second polynomial from the first, we combine like terms: $3x^2y - 5x^2y = -2x^2y$, $-2xy - 4xy = -6xy$, and there's no $x y^2$ term in the first polynomial, so $-2 x y^2$ remains as is.

Subtract - (3x2y−2xy)−(5x2y+2xy2+4xy)\left(3 x^{2} y-2 x y\right)-\left(5 x^{2} y+2 x y^{2}+4 x y\right)(3x2y−2xy)−(5x2y+2xy2+4xy)

Subtract
- $\left(3 x^{2} y-2 x y\right)-\left(5 x^{2} y+2 x y^{2}+4 x y\right)$
