The question is Use IDLE to calculate the 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 don't know how to code this so I don't have a code to attach.

Since you end up having to find the square root of a negative number you need to use the cmath library that can handle complex numbers. I attached a program that does this. Hope this helps.

That's not quite correct since the minus cancel out in the root so the solution will be real for this particular problem

That simplifies the answer :-)
