Objective:
- You will create a program that calculates the quadratic formula from given user input
Directions:
- Create a program, where you prompt the user (ask the user for input) for variables a, b, and c
- Calculate both real solutions using the quadratic formula (look it up on the internets)
- Reminder: There are two roots to calculate
- HINT: exponentiation: x**y (x to the y power)
- HINT2: square root is the same as taking something to the power 0.5
- Print the quadratic equation: a*x^2 + b*x + c = 0
- Print the two real solutions of the quadratic formula
- CHALLENGE: check if the solutions are real or imaginary
- CHALLENGE2: print both solutions even if imaginary
