Write in Standard Form 9x^2y-4x+3y^3x-2y^2

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

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

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

Move $y^{3}$ .

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

Move $- 4 x$ .

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

Reorder $9 x^{2} y$ and $3 x y^{3}$ .

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