Objective:

  • You will create a program that calculates the quadratic formula from given user input

Directions:

  1. Create a program, where you prompt the user (ask the user for input) for variables a, b, and c
  2. Calculate both real solutions using the quadratic formula (look it up on the internets)
    1. Reminder: There are two roots to calculate
    2. HINT: exponentiation: x**y (x to the y power)
    3. HINT2: square root is the same as taking something to the power 0.5
  3. Print the quadratic equation: a*x^2 + b*x + c = 0
  4. Print the two real solutions of the quadratic formula


  1. CHALLENGE: check if the solutions are real or imaginary
  2. CHALLENGE2: print both solutions even if imaginary

Examples:

Please enter a: 1
Please enter b: 3
Please enter c: 2

Your equation is 1*x^2+3*x+2=0
The roots are:
-1.0
-2.0
