a = 1; b = 0.96; c = 0;
Δ = b2-4ac
Δ = 0.962-4·1·0
Δ = 0.9216
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{-(0.96)-\sqrt{0.9216}}{2*1}=\frac{-0.96-\sqrt{0.9216}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0.96)+\sqrt{0.9216}}{2*1}=\frac{-0.96+\sqrt{0.9216}}{2}
