Question

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

–5x3y3 + 8x4y2 – xy5 – 2x2y4 + 8x6 + 3x2y4 – 6xy5

Answer 1

Answer:
`-5x^3y^3+8x^4y^2-7xy^5+x^2y^4+8x^6`

Explanation:

`-5x^3y^3+8x^4y^2-xy^5-2x^2y^4+8x^6+3x^2y^4-6xy^5`

`-5x^3y^3+8x^4y^2+(-xy^5-6xy^5)+(-2x^2y^4+3x^2y^4)+8x^6`

`-5x^3y^3+8x^4y^2+(-7xy^5)+(x^2y^4)+8x^6`

`-5x^3y^3+8x^4y^2-7xy^5+x^2y^4+8x^6`

Answer 2

D. 8x6 + 8x4y2 – 5x3y3 + x2y4 – 7xy5
