public static final double[] solveQuadric(double a,
                                          double b,
                                          double c)
```
    Solves the equation ax^2+bx+c=0. Solutions are returned in a sorted array if they exist.
    
    Parameters:
    
    a - coefficient of x^2
    
    b - coefficient of x^1
    
    c - coefficient of x^0
    
    Returns:
    
    an array containing the two real roots, or null if no real solutions exist
  - solveQuartic
```
public static double[] solveQuartic(double a,
                                    double b,
                                    double c,

                                    double e)
```
    Solve a quartic equation of the form ax^4+bx^3+cx^2+cx^1+d=0. The roots are returned in a sorted array of doubles in increasing order.
    
    Parameters:
    
    a - coefficient of x^4
    
    b - coefficient of x^3
    
    c - coefficient of x^2
    
    d - coefficient of x^1
    
    e - coefficient of x^0
    
    Returns:
    
    a sorted array of roots, or null if no solutions exist
