For a general quadratic equation y = ax? + bx + c, the roots can be classified into
three categories depending upon the value of the discriminant which is given by
b2 - 4ac
First, if the discriminant is equal to 0, there is only one real root. Then, if the discriminant
is a positive value, there are two roots which are real and unequal. The roots can be
computed as follows:
-b+ Vb? – 4ac
2a
Further, if the discriminant is a negative value, then there are two imaginary roots. In
this case, the roots are given by
b
ь? - 4ас
2a

Each line represents the values of a, b and c, for a quadratic equation. Write a program
that read these coefficient values, calculate the roots of each quadratic equation, and display
the results. Your program should perform the following tasks:
• Check if the file is successfully opened before reading
• Use loop to read the file from main function
• Use programmer-defined function named calcRoots () to calculate the roots
• Display the type of roots and the root(s) for each equation to console screen.
Format the output to be displayed in floating point numbers, which set to two (2)
decimal places of precision.
