x^2-33.2=0

a = 1; b = 0; c = -33.2;
Δ = b2-4ac
Δ = 02-4·1·(-33.2)
Δ = 132.8
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{132.8}}{2*1}=\frac{0-\sqrt{132.8}}{2}
=-\frac{\sqrt{}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{132.8}}{2*1}=\frac{0+\sqrt{132.8}}{2}
=\frac{\sqrt{}}{2}
