Re arrange your equation a little bit $x^2-6x+22=0$ your a times c is equal to 22, it's factors are 11 and 2, now you can't use 11 and 2 such that they add up to 6, because they are the only factors u can multiply to get 22, so a different method must be used, do you know the quadratic formula??here it is for a quadratic equation of the form $ax^2+bx+c=0$ $x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$

$x^2-6+22=0$$x=\frac{ -6\pm \sqrt{6^2-4(1)(22)} }{ 2 }$$x=3+\sqrt{13}i$$x=3-\sqrt{13}i$

you have a complex number here

depends on the context of your question, it can either be considered undefined or the complex number answer

i think it is the answer because it is a choice, so thank you!
