Extracted text: Illustrate your knowledge of C-Programming by writing a user defined function to solve the quadratic equation. Function will take a, b and c as input and compute and return both the roots of the quadratic equation. If roots are imaginary, function will return -1 as the error value for both the roots. In main(), ask the user to enter values Page 1 of 3 of a, b and c and call the user defined function. At the end, main() will display both the roots returned by the function on screen. -6±/6²–4ac x = 2a
