Evaluate 7x^2y^2+12xy^2-3x^2y+11+4xy-13x^2y+7

$7 x^{2} y^{2} + 12 x y^{2} - 3 x^{2} y + 11 + 4 x y - 13 x^{2} y + 7$

Step 1

Subtract $13 x^{2} y$ from $- 3 x^{2} y$ .

$7 x^{2} y^{2} + 12 x y^{2} - 16 x^{2} y + 11 + 4 x y + 7$

Step 2

Add $11$ and $7$ .

$7 x^{2} y^{2} + 12 x y^{2} - 16 x^{2} y + 4 x y + 18$
