When $$\(a \ne 0\)$$, there are two solutions to \(ax^2 + bx + c = 0\) and they are
$x = {-b \pm \sqrt{b^2-4ac} \over 2a}.$
We study the addition of two {\scriptsize M \times N} rectangular random matrices with certain
invariant distributions in two limit regimes, where the parameter {\scriptsize \beta}
… we have `\(x_1 = 132\)` and `\(x_2 = 370\)` and so …
