Add the following `5y^2x^2, -6xy, 8x^2y^2, 3xy`

Identify like terms in the following – xy^2, – 4yx^2, 8x^2, 2xy^2, 7y, – 11x^2, – 100x, – 11yx, 20x^2y, – 6x^2, y, 2xy, 3x

Add the following expressions: x^3 - x^2y - xy^2 - y^3 and x^3-2x^2y + 3xy^2 + 4y

2.Add the following: 12x-10y+16xy-8,-6x+12y-10xy+16

Simplify the following: 17x^2y-3xy^2+14x^2y+2xy^2

Simplify the following : 2x^(2)+3y^(2)-5xy+5x^(2)-y^(2)+6xy-3x^(2)

Simplify the following : 3xy^(2) - 5x^(2)y + 7xy - 9xy^(2) - 4xy + 6x^(2)y

Add the following expressions: x^(2)-2xy+3y^(2), 5y^(2)+3xy-6x^(2)

Simplify the following : 2x^(2) + 3y^(2) - 5xy +5x^(2) - y^(2) + 6xy - 3x^(2)

Subtract the second polynomial form the first: 8x^2 +4y^2 -6y+8 , x^2 -5y^2 +2xy +3y -8

2x^2+6xy+5y^2=1, then
