a = 3; b = 0; c = -18.72;
Δ = b2-4ac
Δ = 02-4·3·(-18.72)
Δ = 224.64
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{224.64}}{2*3}=\frac{0-\sqrt{224.64}}{6}
=-\frac{\sqrt{}}{6}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{224.64}}{2*3}=\frac{0+\sqrt{224.64}}{6}
=\frac{\sqrt{}}{6}
