[Solved] : Question 134899

The roots of the quadratic equation 0 ax bx 2 1 1 c 5 , a ≠ 0 are given
by the following formula:
4
2
2 6b b2 2 ac
a
In this formula, the term 4 b a 2 2 c is called the discriminant. If
4 0 b a 2 2 5c , then the equation has a single (repeated) root. Ifb a 2 2 .c , the equation has two real roots. If 4 0 b a 2 2 ,c , the
equation has two complex roots. Write a program that prompts the
user to input the value of a (the coefficient of 2 x ), b (the coefficient
of x), and c (the constant term) and outputs the type of roots of the
equation. Furthermore, if 4 0 b a 2 2 $c , 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.)
