kramer

$x^2-5x+6=0$

$x=\frac{-(-5)\pm\sqrt{(-5)^2-4\times1\times6}}{2\times1}\Leftrightarrow$

$\Leftrightarrow x=\frac{5\pm\sqrt{25-4\times6}}{2}\Leftrightarrow$

$\Leftrightarrow x=\frac{5\pm\sqrt{25-24}}{2}\Leftrightarrow$

$\Leftrightarrow x=\frac{5\pm\sqrt{1}}{2}\Leftrightarrow$

$\Leftrightarrow x=\frac{5\pm1}{2}\Leftrightarrow$

$\Leftrightarrow x=\frac{5-1}{2}\;\;\;\vee\;\;\;x=\frac{5+1}{2}\Leftrightarrow$

$\Leftrightarrow x=\frac{4}{2}\;\;\;\vee\;\;\;x=\frac{6}{2}\Leftrightarrow$

$\Leftrightarrow x=2\;\;\;\vee\;\;\;x=3$

Answer: $x\in\{2\;;\;3\}$
