solveQuadraticback to summary
public static int solveQuadratic(double[] eqn, double[] res)

[A double version of what is in QuadCurve2D...] Solves the quadratic whose coefficients are in the eqn array and places the non-complex roots into the res array, returning the number of roots. The quadratic solved is represented by the equation: 

    eqn = {C, B, A};
    ax^2 + bx + c = 0
A return value of -1 is used to distinguish a constant equation, which might be always 0 or never 0, from an equation that has no zeroes.
Parameters
eqn:double[]

the specified array of coefficients to use to solve the quadratic equation

res:double[]

the array that contains the non-complex roots resulting from the solution of the quadratic equation

Returns:int

the number of roots, or -1 if the equation is a constant.
