Δ = b2-4ac
Δ = 02-4·(-1)·1.21
Δ = 4.84
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$s_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{4.84}}{2*-1}=\frac{0-\sqrt{4.84}}{-2}
=-\frac{\sqrt{}}{-2}
$
$s_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{4.84}}{2*-1}=\frac{0+\sqrt{4.84}}{-2}
=\frac{\sqrt{}}{-2}
