a = 64; b = 24; c = +2;
Δ = b2-4ac
Δ = 242-4·64·2
Δ = 64
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$i_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$i_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{64}=8$
$i_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(24)-8}{2*64}=\frac{-32}{128} =-1/4 $
$i_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(24)+8}{2*64}=\frac{-16}{128} =-1/8 $
