a = 3; b = 0; c = -3.888;
Δ = b2-4ac
Δ = 02-4·3·(-3.888)
Δ = 46.656
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{46.656}}{2*3}=\frac{0-\sqrt{46.656}}{6}
=-\frac{\sqrt{}}{6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{46.656}}{2*3}=\frac{0+\sqrt{46.656}}{6}
=\frac{\sqrt{}}{6}
