a = 0.5; b = 0; c = -3;
Δ = b2-4ac
Δ = 02-4·0.5·(-3)
Δ = 6
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$r_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$r_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$r_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{6}}{2*0.5}=\frac{0-\sqrt{6}}{1}
=-\frac{\sqrt{}}{1}
$
$r_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{6}}{2*0.5}=\frac{0+\sqrt{6}}{1}
=\frac{\sqrt{}}{1}
