$9 x y^{3} - 4 y^{4} - 10 x^{2} y^{2} + x^{3} y + 3 x^{4} + 2 x^{2} y^{2} - 9 y^{4}$

Step 1

Subtract $9 y^{4}$ from $- 4 y^{4}$ .

$9 x y^{3} - 13 y^{4} - 10 x^{2} y^{2} + x^{3} y + 3 x^{4} + 2 x^{2} y^{2}$

Step 2

Add $- 10 x^{2} y^{2}$ and $2 x^{2} y^{2}$ .

$9 x y^{3} - 13 y^{4} + x^{3} y + 3 x^{4} - 8 x^{2} y^{2}$
