Which polynomial correctly combines the like terms and expresses the given polynomial in standard form?

9xy3 – 4y4 – 10x2y2 + x3y + 3x4 + 2x2y2 – 9y4

–13y4 + 3x4 – 8x2y2 + x3y + 9xy3

–13y4 + x3y – 8x2y2 + 9xy3 + 3x4

3x4 – 8x2y2 + x3y + 9xy3 – 13y4

3x4 + x3y – 8x2y2 + 9xy3 – 13y4

Option 4 is correct

Step-by-step explanation:

We have been given the polynomial

Like terms are those have same variables

For example

And

Rest of the terms do not have like terms after combining the like terms we get

After simplification we get

After arranging them in standard form we get

Hence, Option 4 is correct

45
