Take away : `(y^3)/3+7/3y^2+1/2y+1/2\ from1/3-5/3y^2`

((y^(3)-3y^(2)+5y-1)/(y-1))

x^(3)-y^(3)+3y^(2)-3y+1

Subtract : 5y^(4) - 3y^(3) + 2y^(2) + y - 1 from 4y^(4) - 2y^(3) - 6y^(2) - y + 5

From (a) 1-5y^2, take away y^3+7y^2+y+1 (b) x^3-5x^2+3x+1, take away 6x^2-4x^3+5+3x

From (a) 1-5y^2, take away y^3+7y^2+y+1 (b) x^3-5x^2+3x+1, take away 6x^2-4x^3+5+3x

Evaluate : (x^(1//3)+y^(1//3))(x^(2//3)-x^(1//3)y^(1//3)+y^(2//3)) , when x=4(5)/(7) " and " y=5(2)/(7) .

Subtract: x^2y-4/5x y^2+4/3x y\ from 2/3x^2y+3/2x y^2-1/3x y

Subtract : (-2y^2+1/2y-3)\ from\ 7y^2-2y+10.
