The roots of the quadratic equation ax² + bx + c = 0, a ≠ 0 are given by the following formula:

Quadratic Formula
In this formula, the term b² - 4ac is called the discriminant. If b² - 4ac = 0, then the equation has a single (repeated) root. If b² - 4ac > 0, the equation has two real roots. If b² - 4ac < 0, the equation has two complex roots.

Instructions
Write a program that prompts the user to input the value of:

a (the coefficient of x²)
b (the coefficient of x)
c (the constant term)
The program then outputs the type of roots of the equation.

Furthermore, if b² - 4ac ≥ 0, the program should output the roots of the quadratic equation.

(Hint: Use the function pow from the header file cmath to calculate the square root. Chapter 3 explains how the function pow is used.)

Format your output with a decimal precision of 2.
