Ask the user for the coefficients a, b and c of a quadratic equation ax + bx +c = 0. Implement solving for the roots of the quadratic equation. If there is only one root, print it. If the roots are complex, print an error message. You are required to: • Write a function to determine and return the determinant b - 4ac from the coefficients. (Hint: This function will make it easy for you to tell how many roo the equation has...) --b+Ÿ&-4ac 2a • Write a function to determine and return the first root from the coefficients. • Write a function to determine and return the second root from the coefficients. 2a It's up to you how to put together the conditions and output from there.

Question
I attached the code & output. I am not getting -0.5 and -2.0 when a= 2.0, b= 5.0, and c=2.0. Could you show me step by step how to solve this. Please read the question carefully. Thanks!
