Title
Body
I am trying to write a function in C++ that solves for X using the quadratic equation. This is what I have written initially, which seems to work as long as there are no complex numbers for an answer: float solution1 = (float)(-1.0 * b) + (sqrt((b * b) - (4 * a * c))); solution1 = solution1 / (2*a); cout << "Solution 1: " << solution1 << endl; float solution2 = (float)(-b) - (sqrt((b*b) - (4 * a * c))); solution2 = solution2 / (2*a); cout << "Solution 2: " << solution2; If, for example, I use the equation: x^2 - x - 6, I get the solution 3, -2 correctly. My question is how would I account for complex numbers....for example, given the equation: x^2 + 2x + 5 Solving by hand, I would get -1 + 2i, -1 - 2i. Well, I guess two question, can I write the above better and also make it account for the complex number? Thanks for any help!
