[tex]\boldsymbol{ \red{ S = \{(1;0)\} }}[/tex]

Explicație pas cu pas:

[tex]\begin{cases}y = x^2 - 4x + 3\\x^2 - y = 1 \end{cases} \Rightarrow \begin{cases}x^2 - y = 4x - 3\\x^2 - y = 1 \end{cases}[/tex]

[tex]\Rightarrow 4x - 3 = 1 \Rightarrow x = 1[/tex]

[tex]1 - y = 1 \Rightarrow y = 0[/tex]

[tex]\boldsymbol{ S = \{(1;0)\} }[/tex]
