Simplify: `5+[x-{2y-(6x+y-4)+2x^2}-(x^2-2y)]`

Simplify: 5 (x + 3y) -2 (3x-4y)

Simplify: x^2(x+2y)(x-3y)

Simplify: (x^2-2y^2)(x+4y)x^2y^2

Simplify: x/(x-y)-y/(x+y)-(2x y)/(x^2-y^2)

5.Simplify : 2x-[3y-{2x-(y-x)}]

Simplify: x^2(x-y)+y^2(x+2y)

Simplify : (3x+2y)^3-(5x+y)^3 .

Simplify: (3x+2y)(4x+3y)-\ (2x-y)(7x-3y)
