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?
