x^2-67.821=0

a = 1; b = 0; c = -67.821;
Δ = b2-4ac
Δ = 02-4·1·(-67.821)
Δ = 271.284
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{271.284}}{2*1}=\frac{0-\sqrt{271.284}}{2}
=-\frac{\sqrt{}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{271.284}}{2*1}=\frac{0+\sqrt{271.284}}{2}
=\frac{\sqrt{}}{2}
