Tim 3 so nguyen to lien tiep x,y,z (x<y<z) thoa man A = x^2 + y^2 + z^2 la so nguyen to
tim cap so nguyen (x;y) thoa man : |x+2| + (y+2)2 = 3 - |x+1|
tim so nguyen duong x,y thoa man : x^2=1!+2!+3!+....+y!
tim cac so nguyen x,y biet x^2-(y-3)x-2y-1=0
tim cap so nguyen x,y thoa man: |x+4|+|y-2|=3
tim cac so nguyen x de y =2x-3 phan x-2
