Объяснение:
[tex] {x}^{2} - 13x + 22 = 0[/tex]
По теореме Виета:
[tex]{x}^{2} + bx + c = 0\\ x_{1} + x_{2} = - b\\ x_{1} x_{2} = c[/tex]
[tex]x_{1} + x_{2} =13 \\ x_{1} x_{2} =22 \\ x_{1} = 11 \\ x_{2} = 2 [/tex]
[tex] a{x}^{2} + bx + c = a(x - x_{1})(x - x_{2}) \\ {x}^{2} - 13x + 22 = (x - 2)(x - 11)[/tex]
[tex] \frac{ {x}^{2} -1 3x + 22 }{x - 11} = \frac{(x - 2)(x - 11)}{x - 11} = x - 2[/tex]
