Code not working

Question

I am new to python. My code isn't displaying desired result

import cmath

a,b,c = 5,6,2
quadratic_formula = (-b+cmath.sqrt(b**2-4*a*c))/2*a
print(quadratic_formula)

Answer 1

What's the error that you are getting from the code you provided though?

Answer 2

The code you provided runs fine from other online Python interpreters that I've tried. This for instance:

Answer 3

Yes you use math here. Oh wait I think you're good with C / C++ cuz cmath exists.

Answer 4

@Hatsy
1) Use Python 3 docs.
2) I think cmath should exist, just that it needs to be pip-installed.

Answer 5

Does math library work in the place of cmath? I am using PyCharm as IDE for python. It says math module doesn't exist.

Answer 6

The online interpreters compute this result (-15+5j). Instead there should be a floating point value isn't it?

Answer 7

No error though. Blank

Answer 8

That's strange. Then it might be a problem in PyCharm
