a = 1; b = -144; c = 0;
Δ = b2-4ac
Δ = -1442-4·1·0
Δ = 20736
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$g_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$g_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{20736}=144$
$g_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-144)-144}{2*1}=\frac{0}{2}
=0
$
$g_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-144)+144}{2*1}=\frac{288}{2}
=144
