a = 32; b = -204; c = +221;
Δ = b2-4ac
Δ = -2042-4·32·221
Δ = 13328
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{13328}=\sqrt{784*17}=\sqrt{784}*\sqrt{17}=28\sqrt{17}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-204)-28\sqrt{17}}{2*32}=\frac{204-28\sqrt{17}}{64} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-204)+28\sqrt{17}}{2*32}=\frac{204+28\sqrt{17}}{64} $
