若X^2+Y^2=6X-4Y-13,则X^Y=多少若X^2+Y^2=6X-4Y-13,则X^Y=多少若X^2+Y^2=6X-4Y-13,则X^Y=多少由已知,得(x-3)^2+(y+2)^2=0所以x
若X^2+Y^2=6X-4Y-13,则X^Y=多少
若X^2+Y^2=6X-4Y-13,则X^Y=多少
若X^2+Y^2=6X-4Y-13,则X^Y=多少
由已知,得
(x-3)^2+(y+2)^2=0
所以x=3,y=-2
x^y=3^(-2)=1/9
若X^2+Y^2=6X-4Y-13,则X^Y=多少
设x,y满足x+3y+|3x-y|=19,2x+y=6则X= Y=
把(x+y),(x-y)个作为一个整体合并同类项1,7(x+y)-2(x+y)-4(x+y)+2(x+y)2,(x-y)²+2(x-y)-(x-y)-2(x-y)²
若x+2y=-5,x-4y=15,则x-2y=
已知x+4x+y-6y+13=0.求x+y分之x-2y的值
若x+y-4x-2y=0,求x+y最大值
因式分解4(x-y)^2-12(y-x)+y
已知x和y满足x+3y+|3x-y|=19,2x+y=6,求x,y的值
若x+y=4,则多项式½(x+y)+4﹙x-y)-3(x-y)-3/2(x+y)-x+y是多少?
若(x-y)/(x+y)=3 则(x+2y)/(6x-7y)等于
已知x-y=1,y≠0,求{(x+2y)²+(2x+y)(x+4y)-3(x+y)(x-y)}÷y的值.
若实数x,y满足x+2y-2=0,则3^x+9^y的最小值
若(5x+2y-12)²+|3x+2y-6|=0,则2x+4y=——
若3x+2y=4,6x-4y=3,则9x²-4y²=多少
[(x+2y)(x-2y)+4(x-y)²]÷6x
把6x(x-y)的平方+3(y-x)的立方分解因式我知道答案是6x(x-y)^2+3(y-x)^3=6x(x-y)^2-3(x-y)^3=3(x-y)^2[2x-(x-y)]=3(x-y)^2(x+y)可为什么=6x(x-y)^2-3(x-y)^3=3(x-y)^2[2x-(x-y)]
设变量x,y满足约束条件 2x-y≤2,x-y≥-1,x+y≥1.则z=4x+6y的最大值和最小值
若4x+3y+5=0,则3(8y-x)-5(x+6y-2)的值是多少?
