Simplify (2xy-5x^2y-6xy^2+4x^2y)-(5xy-3xy^2+8xy-3x^2y+12xy^2)

$(2 x y - 5 x^{2} y - 6 x y^{2} + 4 x^{2} y) - (5 x y - 3 x y^{2} + 8 x y - 3 x^{2} y + 12 x y^{2})$

Step 1

Simplify each term.

Add $5 x y$ and $8 x y$ .

$2 x y - 5 x^{2} y - 6 x y^{2} + 4 x^{2} y - (13 x y - 3 x y^{2} - 3 x^{2} y + 12 x y^{2})$

Add $- 3 x y^{2}$ and $12 x y^{2}$ .

$2 x y - 5 x^{2} y - 6 x y^{2} + 4 x^{2} y - (13 x y + 9 x y^{2} - 3 x^{2} y)$

Apply the distributive property.

$2 x y - 5 x^{2} y - 6 x y^{2} + 4 x^{2} y - (13 x y) - (9 x y^{2}) - (- 3 x^{2} y)$

Simplify.

Multiply $13$ by $- 1$ .

$2 x y - 5 x^{2} y - 6 x y^{2} + 4 x^{2} y - 13 (x y) - (9 x y^{2}) - (- 3 x^{2} y)$

Multiply $9$ by $- 1$ .

$2 x y - 5 x^{2} y - 6 x y^{2} + 4 x^{2} y - 13 (x y) - 9 (x y^{2}) - (- 3 x^{2} y)$

Multiply $- 3$ by $- 1$ .

$2 x y - 5 x^{2} y - 6 x y^{2} + 4 x^{2} y - 13 (x y) - 9 (x y^{2}) + 3 (x^{2} y)$

Remove parentheses.

$2 x y - 5 x^{2} y - 6 x y^{2} + 4 x^{2} y - 13 x y - 9 x y^{2} + 3 x^{2} y$

Step 2

Simplify by adding terms.

Subtract $13 x y$ from $2 x y$ .

$- 11 x y - 5 x^{2} y - 6 x y^{2} + 4 x^{2} y - 9 x y^{2} + 3 x^{2} y$

Add $- 5 x^{2} y$ and $4 x^{2} y$ .

$- 11 x y - x^{2} y - 6 x y^{2} - 9 x y^{2} + 3 x^{2} y$

Add $- x^{2} y$ and $3 x^{2} y$ .

$- 11 x y + 2 x^{2} y - 6 x y^{2} - 9 x y^{2}$

Subtract $9 x y^{2}$ from $- 6 x y^{2}$ .

$- 11 x y + 2 x^{2} y - 15 x y^{2}$
