Find the roots of the equation and compute $a + b + c + d$ for the roots in the form $-a \pm \sqrt{b \pm c \sqrt{d}},$ where $a,$ $b,$ $c,$ and $d$ are positive integers, as roots of the equation:
\[\frac{1}{x} + \frac{1}{x + 4} - \frac{1}{x + 8} - \frac{1}{x + 12} - \frac{1}{x + 16} - \frac{1}{x + 20} + \frac{1}{x + 24} + \frac{1}{x + 28} = 0.\]
