i need help to find out what i need to do to solve this problem
Question :Positive root of the following equation:
34*x^2 + 68*x - 510
Recall:
a*x^2 + b*x + c
x1 = ( - b + sqrt ( b*b - 4*a*c ) ) / ( 2*a)

I tried this on my python shell but getting an error and i think m entering something wrong

It has been awhile since I've done this type of equation...I calculated it as x^2=13, if that helps.

Don't forget to do this:
from math import *
because if you don't, you'll have to do math.sqrt(....), if you just use sqrt without that line, python thinks that you are using your own definition called sqrt.
