若x,y满足等式x方+y方-2x+2y+2=0若x,y满足等式x²+y²-2x+2y+2=0,则x^2010+y^2011=?若x,y满足等式x方+y方-2x+2y+2=0若x,y
若x,y满足等式x方+y方-2x+2y+2=0若x,y满足等式x²+y²-2x+2y+2=0,则x^2010+y^2011=?
若x,y满足等式x方+y方-2x+2y+2=0
若x,y满足等式x²+y²-2x+2y+2=0,则x^2010+y^2011=?
若x,y满足等式x方+y方-2x+2y+2=0若x,y满足等式x²+y²-2x+2y+2=0,则x^2010+y^2011=?
x²+y²-2x+2y+2=0
配方得:
(x-1)²+(y+1)²=0
平方数都是大于等于0的,和为0,所以:
x-1=0
y+1=0
x=1
y=-1
x^2010+y^2011
=1^2010+(-1)^2011
=1-1
=0
(x-1)的平方+(y+1)的平方=0
∴x=1,y=-1
∴原式=1-1=0
X=1 Y=-1
结果为0
若x,y满足等式x方+y方-2x+2y+2=0若x,y满足等式x²+y²-2x+2y+2=0,则x^2010+y^2011=?
