Δ = 8.32
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$c_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-7.2)-\sqrt{8.32}}{2*2}=\frac{7.2-\sqrt{8.32}}{4}
$
$c_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-7.2)+\sqrt{8.32}}{2*2}=\frac{7.2+\sqrt{8.32}}{4}
