C of a quadratic equation in the form ax^2 + bx + c = 0, write Python code to calculate the roots using the quadratic formula. The code should handle cases where the discriminant is negative (resulting in complex roots). Provide comments explaining each step. Example: a=1, b=-3, c=2. Expected output:
Calculate discriminant
discriminant = b2 – 4ac
… (rest of the code)’. See how much more specific that is?
What if Llama 2 keeps giving me the wrong answer, even with a ‘good’ prompt? What do I do?
Don’t panic! First, double-check your prompt for ambiguity or errors. Are you accidentally leading Llama 2 astray? Try rephrasing the prompt or breaking it down further.
