[(x+2y)^2-(x-2y)^2-(x-2y)(x+2y)-4y^2]/2x
=[x^2+4xy+4y^2-(x^2-4xy+4y^2)-(x^2-4y^2)-4y^2]/2x
=(x^2+4xy+4y^2-x^2+4xy-4y^2-x^2+4y^2-4y^2)/2x
=(8y-x)/2

1、x(x-y)(x+y)-x(x+y)^2 化简：（2x-y)²-4(x-y)(x+y) x^2-y^2/x+y-4x(x-y)+y^2/2x-y, 化简:(x-3y)(x+y)-(x-2y)(x+2y)-(x-y)平方 (1)(x^2/x)-y-x-y 【(x-y)^2+(x+y)(x-y)】除以 2x (2x-y)^2-4(x-y)(x+2y) (2x-y)²-4(x-y)(x+2y) {(z+y)(x-y)-(x-y)的2次方+2y(x-y)}除以4y [(-x-y)(-x+y)-(x+y)^2-x(y-y^2)}÷1/2y x+2y+4y^2/x-y+4x^y/4y^2-x^2 4x(y-x)-y^2因式分解
