Methods
$3
#### Arguments
- a: coefficent of the squared term.
- b: coefficient of the linear term.
- c: constant with its sign.
#### Return Value
- when both roots are real: Array[2] with the roots of the equation.
- when only one root is real: Array[2] wherein the first element is the real root and the other element is a warning.
- when both roots are imaginary: Array[2] in which both elements are warnings.
Note: If a is equal to 0, quadSolverCitardauq() will be called automatically with the arguments as provided.
