Solve a quadratic polynomial with real coefficients to get the real roots (GSL)

This is just a wrapper for gsl_poly_complex_solve_quadratic().

Public Functions

virtual int solve_r(const double a2, const double b2, const double c2, double &x1, double &x2)

Solves the polynomial \( a_2 x^2 + b_2 x + c_2 = 0 \) giving the two solutions \( x=x_1 \) and \( x=x_2 \) .
