Δ = b2-4ac
Δ = 52-4·36·0
Δ = 25
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{25}=5$
$h_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5)-5}{2*36}=\frac{-10}{72}
=-5/36
$
$h_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+5}{2*36}=\frac{0}{72}
=0
