\(\left(x+1\right)^2+\left(y-1\right)^2=0\)
\(\Rightarrow\left(x+1\right)^2=0\) và \(\left(y-1\right)^2=0\)
\(\Rightarrow x=-1\) và \(y=1\)
tíc mình nha

tim cac so nguyen x,y biet x^2-(y-3)x-2y-1=0
tim x ,y la so nguyen to biet : x^2 - 6y^2 -1 =0
Tim cac so nguyen x, y biet: x/4 - 1/y =1/2 ( giai chi tiet gium minh nha cac bn . Cam on nhiu!!!!!! )
1 tim cac so nguyen x,y biet x/7=6/21 -5/y=20/28 1/2=x/12 x/8=-28/32 3/y=12/24 3/4=15/y 2 viet 3 phan so bang phan so -10/15
Tim so nguyen x,y biet x^2-y^2=5
tim cap so nguyen X,Y biet 8x(2009-x)^2=25-y^2
tim x,y biet 5x^2 -2xy+ 2y^2=18 ; x,y la so nguyen
tim so nguyen x,y biet 5/x+y/4=1/8
tim cap so x,y nguyen biet :
