若整数x,y满足x²+4x+y²－6y+13=0,求x,y的值

若整数x,y满足x²+4x+y²－6y+13=0,求x,y的值 若整数 x,y 满足x²＋4x＋y²－6y＋13＝0,求x , y的值. 若整数x、y满足x^2 +4x+y^2 -6y+13=0,求x、y的值. 若有理数X、Y满足x²-4x+y²+6y+13=0,求xy的值 已知非零有理数x,y满足x²-4xy+4y²=0,求x-y/x+y-y-x/x+y的值. 若是数xy满足x²+4x+y²-6y+13=0,求x,y的值 已知x,y满足x²+y²-4x+6y+13=0则(3x+y)²-(3x+y)(3x-y)的 若x、y满足2x+y=6,x-3y=1,求7y(x-3y)²-2(3y-x)³的值 若实数x、y满足4x²+y²-4x+6y+10=0,求x²+y²的值 整数x,y满足x2-y2=2xy,求x-y/x+y的值 已知x²+4y²-6x+8y+13=0,求x-y/x+y的值. 若正数x,y满足x²-y²=2xy,求（x-y)/(x+y)的值
