a^2-32a-32=0

Solution for a^2-32a-32=0 equation:

a^2-32a-32=0

a = 1; b = -32; c = -32;
Δ = b2-4ac
Δ = -322-4·1·(-32)
Δ = 1152
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{1152}=\sqrt{576*2}=\sqrt{576}*\sqrt{2}=24\sqrt{2}$
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-32)-24\sqrt{2}}{2*1}=\frac{32-24\sqrt{2}}{2}
$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-32)+24\sqrt{2}}{2*1}=\frac{32+24\sqrt{2}}{2}
