a = 36; b = -13; c = +1;
Δ = b2-4ac
Δ = -132-4·36·1
Δ = 25
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{25}=5$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-13)-5}{2*36}=\frac{8}{72} =1/9 $
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-13)+5}{2*36}=\frac{18}{72} =1/4 $
