------------
First, that's not a question, it's an equation.
I'll assume you want to solve it for x.
x^2+11=6x
{{{x^2 - 6x = -11}}}
It can't be factored, but you can complete the square.
{{{x^2 - 6x - 9 = -11 + 9 = -2}}}
{{{(x-3)^2 = -2}}}
{{{x-3 = +sqrt(-2)}}} and
{{{x-3 = - sqrt(-2)}}}
x = 3 +/- i*sqrt(2)
