x2-12x+26=0
We add all the numbers together, and all the variables
x^2-12x+26=0
a = 1; b = -12; c = +26;
Δ = b2-4ac
Δ = -122-4·1·26
Δ = 40
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{40}=\sqrt{4*10}=\sqrt{4}*\sqrt{10}=2\sqrt{10}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-12)-2\sqrt{10}}{2*1}=\frac{12-2\sqrt{10}}{2} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-12)+2\sqrt{10}}{2*1}=\frac{12+2\sqrt{10}}{2} $
