Using the top–down method, please describe an algorithm for a program to solve the real roots of a quadratic equationax2 + bx + c = 0Your algorithm should ask the user for the coefficients. To calculate the roots of the equation, Your algorithm should calculate the discriminant D given by D = b2 – 4ac. If D > 0, the algorithm displays a message: The equation has two roots and then displays the roots. If D = 0, the algorithm displays a message: The equation has one root, and then displays the root. If D < 0, the algorithm displays a message: The equation has no real roots. Create a flowchart for your algorithm.
