tim cac so nguyen to x,y sao cho x^2-2y^2-1=0 GIUP MINH VOI
Tim so nguyen to x,y sao cho x2_2y2=1
ai giai xong ket ban vs mik nha
Tim x,y la so nguyen
a) 2x-3y+5= xy
b) x mu 2 +2xy+2x+4y
B2 Tim x,y la so nguyen to
x mu 2 -2y mu 2 =1
B3 Tim so tu nhienx,y
7 .(x-2004) mu 2 = 23- y mu 2
tim cac cap so nguyen duong nguyen to cung nhau sao cho: (x+y)/(x^2+y^2)=7/25
tim cac so nguyen x,y biet x^2-(y-3)x-2y-1=0
tim cac cap so nguyen duong nguyen to cung nhau sao cho: (x+y)/(x^2+y^2)=7/25

Cho minh hoi bai nay. Chi can tra loi 1 cau cung duoc! Tick cho ai tra loi som nhat, day du nhat.
1. Cho so huu ti y=2a-1/-3. Voi gia tri nao cua a thi y la so duong, y la so am, khong phai so duong cung phai so am?
2. Cho so huu ti x=a-5/a (a khac 0). Voi gia tri nao cua a thi x la so nguyen?
3. Cho so huu ti x=a-3/2a (a khac 0). Voi gia tri nao cua a thi x la so nguyen?
1.Tim cac cap so nguyen x,y sao cho x+y=2xy
2.Tim GTNN A = x2+3(x-1)2
tim x,y biet 5x^2 -2xy+ 2y^2=18 ; x,y la so nguyen
