(algebra: solve quadratic equations) the two roots of a quadratic equation ax^2 + bx + c = 0 can be obtained using the following formula: r1 = (-b + sqrt(b^2 - 4ac)) / (2a) and r2 = (-b - sqrt(b^2 - 4ac)) / (2a) b^2 - 4ac is called the discriminant of the quadratic equation. if it is positive, the equation has two real roots. if it is zero, the equation has one root. if it is negative, the equation has no real roots. write a program that prompts the user to enter values for a, b, and c and displays the result based on the discriminant. if the discriminant is positive, display two roots. if the discriminant is 0, display one root. otherwise, display "the equation has no real roots".

Let r1 and r2 be the roots of the quadratic equation x2 - 12x + 9 = 0. determine the value of 2 + 2 . (hint: in the first recitation the relationship between the coefficients in a quadratic and the sum and product of the roots of the quadratic was proven. use this relationship to solve the problem without finding either root.)
