$4 x^{2} y^{2} - 2 y^{4} - 8 x y^{3} + 9 x^{3} y + 6 y^{4} - 2 x y^{3} - 3 x^{4} + x^{2} y^{2}$

Step 1

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$a x^{2} + b x + c$

Step 2

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

$- 2 y^{4} - 8 x y^{3} + 9 x^{3} y + 6 y^{4} - 2 x y^{3} - 3 x^{4} + 5 x^{2} y^{2}$

Step 3

Add $- 2 y^{4}$ and $6 y^{4}$ .

$4 y^{4} - 8 x y^{3} + 9 x^{3} y - 2 x y^{3} - 3 x^{4} + 5 x^{2} y^{2}$

Step 4

Subtract $2 x y^{3}$ from $- 8 x y^{3}$ .

$4 y^{4} - 10 x y^{3} + 9 x^{3} y - 3 x^{4} + 5 x^{2} y^{2}$

Step 5
