Thread Starter 
I am building a program for the quadratic formula but it won't execute the sqrt command. I assume that I need the math modual but don't know how to import it. Please help.

For importing the "math" module in Python or any other module for that matter, all you have to include in your code before you wish to execute one of its functions is,
Code:
import <module-name>

In this case,
Code:
import math

I put import math at the top of my program yet it still only says sqrt is not defined.

You may not be using the correct syntax to use the sqrt function. If you want to find the square root of 4, you should have in your code,
Code:
math.sqrt(4)
.

You have to write the library in front of the function name:
Code:
import math

math.sqrt(25)

Alternatively if you wanted to do just
Code:
sqrt(25)

You could do it this way:
Code:
from math import sqrt

sqrt(25)

But ONLY sqrt will be imported and no other function.
