-8x^4y+6x^3y-2x^2y进行因式分解
-8x^4y+6x^3y-2x^2y进行因式分解
-8x^4y+6x^3y-2x^2y
=-2x^2y(4x^2-3x+1)
=-2x^2y(4x^2-3x+1)
-8x^4y+6x^3y-2x^2y进行因式分解
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
4x-3y/x-2y÷6y-8x/y-2x
81/8*(-x-y)^6*(x-y)^3*4/9(x+y)^4*(y-x)^2
[2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2
【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2=
