(x−2)2+2(y−3)2<5,2(y−3)2∈{0,2,8,...}⇒2(y−3)2=0 hoặc 2
- \(2\left(\right.y-3\left.\right)^2=0\Rightarrow y=3\), khi đó \(\left(\right. x - 2 \left.\right)^{2} < 5 \Rightarrow \left(\right. x - 2 \left.\right)^{2} = 0 , 1 , 4 \Rightarrow x = 2 , 3 , 1 , 4 , 0\)
- \(2 \left(\right. y - 3 \left.\right)^{2} = 2 \Rightarrow \left(\right. y - 3 \left.\right)^{2} = 1 \Rightarrow y = 2 , 4\), khi đó \(\left(\right. x - 2 \left.\right)^{2} < 3 \Rightarrow \left(\right. x - 2 \left.\right)^{2} = 0 , 1 \Rightarrow x = 2 , 3 , 1\)
vậy x,y=
\(\left(\right. 0 , 3 \left.\right) , \left(\right. 1 , 3 \left.\right) , \left(\right. 2 , 3 \left.\right) , \left(\right. 3 , 3 \left.\right) , \left(\right. 4 , 3 \left.\right) , \left(\right. 1 , 2 \left.\right) , \left(\right. 2 , 2 \left.\right) , \left(\right. 3 , 2 \left.\right) , \left(\right. 1 , 4 \left.\right) , \left(\right. 2 , 4 \left.\right) , \left(\right. 3 , 4 \left.\right)\)
