Write a MATLAB script file to find the roots of the quadratic equation.If the discriminant is less than zero,equal zero or greater than zero, display as the equation has no real roots,the equation has one root and the equation has two roots respectively. Using the above function display the roots for the following equations. (a) 3x 2 + 6x + 3 = 0 (b) 3x 2 + 4x 6 = 0 (c) 3x 2 + 7x + 5 = 0
