Question

Hi,i was doing this:
Calculate 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 )

My answer
>>> a,b,c=34,68,-510
>>> import math
>>> x1= (-b +math.sqrt(b^2-4*a*c))/(2*a)
>>> x2=(-b -math.sqrt(b^2-4*a*c))/(2*a)
##I should only find positive root so i thought that i can do that way:
if(x1) < 0 ,then x=x2
if(x2) <0 ,then x=x1
print(x)
but there is an error,what am i doing wrong?

Answer 1

what is the error?
have you read the tutorial in the python documentation?
