See the entire solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of the individual terms correctly:

$(-8xy + 3x^2 - 5y) + (4x^2 - 2y + 6xy)$ becomes:

$-8xy + 3x^2 - 5y + 4x^2 - 2y + 6xy$

Next, group like terms:

$3x^2 + 4x^2 + 6xy - 8xy - 5y - 2y$

Now, combine like terms:

$(3 + 4)x^2 + (6 - 8)xy + (-5 - 2)y$

$7x^2 - 2xy - 7y$

How do you find the sum or difference of (-8xy+3x^2-5y)+(4x^2-2y+6xy)(-8xy+3x^2-5y)+(4x^2-2y+6xy)?
