(x-2y)*(x-2y)-4x+8y+4=因式分解(x-2y)*(x-2y)-4x+8y+4=因式分解(x-2y)*(x-2y)-4x+8y+4=因式分解(x-2y)*(x-2y)-4x+8y+4=
(x-2y)*(x-2y)-4x+8y+4= 因式分解
(x-2y)*(x-2y)-4x+8y+4= 因式分解
(x-2y)*(x-2y)-4x+8y+4= 因式分解
(x-2y)*(x-2y)-4x+8y+4
=(x-2y)²-4(x-2y)+4
=(x-2y-2)²(把x-2y看成一个整体再用完全平方公式)
(x-2y)*(x-2y)-4x+8y+4
=(x-2y)²-4(x-2y)+4
=(x-2y-2)²
(x-2y)*(x-2y)-4x+8y+4=(x-2y-2)*(x-2y-2)
1.((y+2x)(-2x+y)+4(x+2y)^2)/3y 2.(2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2)/2(x-y)^2
(x-y)(x-y)2(y-x) (x+2y-?)(x-2y+?)
{(x²+y²)-(x-y)+2y(x-y)}/4y
[(2x+y)的平方-y(y++4x)-8x]/2x
y'=(y/x)^2+y/x+4微分方程
(y-x)^4(x-y)^3+2(x-y)^6(y-x)
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
12(x+y)^3(y-x)/【4(x+y)^2(x-y)】
(x-2y)²+(2x-4y)(x+y)+(x+y)²
(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
计算:[(x+y)³-2(x+y)²-4(x+y)]÷(x+y)
2分之x+y+3分之x-y;4(x+y)-(x-y)谢谢了,
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
(x-2y)(x+y)+(x+y)计算
计算:(x-y)^2-(x+y)(x-y)
2(x-y)²-3(x-y)(-y-x)
2(x-y)+3(x+y)2-5(x-y)-8(x+y)2-(x-y)
化简x+y分之x²-y²-2X-y分之4x(x-y)+y²
