The correct way to solve quadratic equations is none of the above. For the correct algorithm as applied in the following function, seenumerical recipes in C and the Wolfram site at http://mathworld.wolfram.com/QuadraticEquation.html#include bool quadratic(double a, double b,...

I am reposting this because I accidentally deleted my first post.The solution is presented as a pair of complex roots, unless a == 0, in which case the equation is linear and returns a single complex(real) root.If a == 0 and b == 0, the function fails.Given a complex type, replace...
