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.
have you read the Tutorial in the Python docs?? http://dpaste.com/905836/
Should be roots of -5 and 3
