The quadratic formula is \(a x^2 + b x + c = 0 \)
The solutions to the quadratic formula are \(x = \frac{-b \pm \sqrt{b^2 - 4 a c}}{2a}\)
You can compute the hex digits of \(\pi\) using the BBP digit extraction series: \(\pi = \displaystyle\sum_{i=0}^\infty \frac{1}{16^n} ( \frac{4}{8 n + 1} - \frac{2}{8 n + 4} - \frac{1}{8 n + 5} - \frac{1}{8 n + 6}) \)
