Question

simplify.
\left(6x^{2}y - 3y^{2} + 2x\
ight) + \left(xy^{2} + 4x - 7x^{2}y\
ight)

Explanation:

Step1: Remove parentheses

$6x^2y - 3y^2 + 2x + xy^2 + 4x - 7x^2y$

Step2: Combine $x^2y$ terms

$6x^2y - 7x^2y = -x^2y$

Step3: Combine $x$ terms

$2x + 4x = 6x$

Step4: Rewrite with all terms

$-x^2y - 3y^2 + xy^2 + 6x$

Answer:

$-x^2y + xy^2 - 3y^2 + 6x$
