Divide: `x^(7)y-xy^(7)` by `(x+y)(x^(2)-xy+y^(2))`

3x^(2)-20xy-7y^(2)

x-x^(2)y+xy^(2)-y

The factors of x^(3)-x^(2)y-xy^(2)+y^(3) are (a (x+y)(x^(2)-xy+y^(2))(b)(x+y)(x^(2)+xy+y^(2))(c)(x+y)^(2)(x-y)(d)(x-y)^(2)(x+y)

Subtract the second polynomial from the first : 3x^(2)y-7xy^(2) +5xy, 2xy-x^(2)y +7xy^(2)

If x:y::5:2, then (x ^(2) - xy + y ^(2))/( x ^(2) + xy + y ^(2)) = ?

Solve (9x+7xy +9x^(2)) + (8+x^(2) -xy -y^(2)+1) .

If log_((x+y))(x - y) = 7 , then the value of log_((x^(2)-y^(2)))(x^(2)+2xy+y^(2)) is ______.

Subtract 6xy - 4x^(2) - y^(2) - 2 from x^(2) - 3xy + 7y^(2) + 5
