绝度值3x-2y-21+(3x-4y-3)的平方=0,求x的y次方
绝度值3x-2y-21+(3x-4y-3)的平方=0,求x的y次方
绝度值3x-2y-21+(3x-4y-3)的平方=0,求x的y次方
3x+2y—2的绝对值的平方+(y-3)的平方=0,求x的y次方的值
3x+2y—2=0,y-3=0
解出
y=3,x=-4/3
x的y次方=-64/27
(x-y) (x-2y)+(x+2y) (x-3y)-2(x-3y) (x-4y)=
(x+3y-4)(2x-y)
计算(2x-3y)(x+4y)-(3x+y)(x-2y)(2x-3y)(x+4y)-(3x+y)(x-2y)
因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+(x-3y)(x-5y)+(x-2y)(x-4y)
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
(2x+y)(2x-3y)+x(2y+y) 2a(x-y)-4b(x-y)
x(x-y)2-(y-x)3
(y-x)+x(x-y)^3-(y-x)^4 因式分解
[2/3x-2/x+y(x+y/3x-x-y)]/x-y/x
化简:{2/3x-2/(x+y)[(x+y)/3x-x-y]}/(x+y)/x
计算2/3x-2/x+y(x+y/3x-x-y)/x-y/x
化简3x-2/(x+y)[(x+y)/3x-x-y]÷(x-y)/x
(3x-y)(y+3x)-2(4x-3y)(4x+3y)
(x-3y)(y+2x)-(4y-3x)(3x+4y)计算
5/4(x+y)(-x-y)^3*[-4/3(x-y)]*[-3/5(y-x)^2]
(2x-y)(2x+y)-2(3x-4y)(4y+3x)
2(x+y)-3(x-y)=3 ,4(x+y)+3(x-y)=15
5x^3y(x-y)^3-10x^4y^3(y-x)^2因式分解
