4-6 on matlab 4. Write a program in a script file that determines the real roots of a quadratic equation ax2+bx+c 0 When the file runs, it asks the user to enter the values of the constants a, b, and c. To calculate the roots of the equation the program calculates the discriminant D, given by: D b2-4ac When D 0, the program displays message "The equation has two roots," and the roots are displayed in the next line. When...
