Answer: [D] -16x^4y + 4xy^4 + 16xy
Remove parentheses: <u>(-a) = -a</u>
-3xy^4 - 7x^4y + 7xy - 9x^4y + 9xy + 7xy^4
Group like terms
-7x^4y - 9x^4y - 3xy^4 + 7xy^4 + 7xy + 9xy
Add similar elements: <u>-7x^4y - 9x^4y = -16x^4y</u>
= -16x^4y - 3xy^4 - 7xy^4 - 16xy
Add similar elements: <u>-3xy^4 + 7xy^4 = 4xy^4</u>
= -16x^4y + 4xy^4 + 16xy
