Δ = b2-4ac
Δ = 02-4·(-1)·4.732
Δ = 18.928
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{18.928}}{2*-1}=\frac{0-\sqrt{18.928}}{-2}
=-\frac{\sqrt{}}{-2}
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{18.928}}{2*-1}=\frac{0+\sqrt{18.928}}{-2}
=\frac{\sqrt{}}{-2}
