Which polynomial correctly combines the like terms and expresses the given polynomial in standard form? 9xy3 â€"" 4y4 â€"" 10x2y
Aleksandr-060686 [28]

The first option is correct here: -13y^4 + 3x^4 - 8x^2y^2 + x^3y + 9x y^3

<h3>Given the polynomial:</h3>

9xy^3 - 4y^4 - 10x^2y^2 + x^3y + 3x^4 + 2x^2y^2 - 9y^4

<h3 /><h3>Simplification:</h3>

Combine the like terms together as shown below:

9xy^3 - 4y^4 - 10x^2y^2 + x^3y + 3x^4 + 2x^2y^2 - 9y^4\\= (-4y^4 - 9y^4)  + 9xy^3 + (-10x^2y^2 + 2x^2y^2) +x^3y +3x^4\\= -13y^4 +9xy^3 -8x^2y^2 + x^3y + 3x^4\\= -13y^4 +3x^4  -8x^2y^2 + x^3y + 9xy^3

Thus, the first option is correct here: -13y^4 + 3x^4 - 8x^2y^2 + x^3y + 9x y^3
