" 16."quad x(x+y)^(3)-3x^(2)y(x+y)

for x=3 and y=-2 verify that (x-y)^(3)=x^(3)-y^(3)-3xy(x-y)

((x +y)^(3) + (x-y)^(3))/(2) -y (3x^(2) + y^(2)) = ______

The value of (x-y)^3+(x+y)^3+3(x-y)^2(x+y)+3(x+y)^2(x-y) is

Solve for (x - 1)^(2) and (y + 3)^(2) , 2x^(2) - 5y^(2) - x - 27y - 26 = 3(x + y + 5) and 4x^(2) - 3y^(2) - 2xy + 2x - 32y - 16 = (x - y + 4)^(2) .

Simplify : ( 3y ( x - y) - 2x ( y -2x))/( 7x ( x - y) - 3 ( x ^(2) - y ^(2)))

For x = 2 and y = -3, verify the following: (x+y)^(3)=x^(3)+y^(3)+3x^(2)y+3xy^(2)
