Create a function called quadform( ) that takes as input the coefficients of the quadratic equation (a,b,c) and returns the two distinct real roots (x1,x2) as output, if they exist. in addition, the function returns a message (flag) that informs the user if an error occurred when trying to find two distinct real roots. the possible errors are: (1) "only one root is found"; (2) "imaginary roots are found"; (3) "any value of x is a solution"; (4) "no zeroes exist." if no errors occur, then flag should be "no errors".
