a = 1; b = 0; c = -1.96;
Δ = b2-4ac
Δ = 02-4·1·(-1.96)
Δ = 7.84
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{7.84}}{2*1}=\frac{0-\sqrt{7.84}}{2} =-\frac{\sqrt{}}{2} $
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{7.84}}{2*1}=\frac{0+\sqrt{7.84}}{2} =\frac{\sqrt{}}{2} $
