In the getting started pdf it gives two practice exercises to do to get you acquainted with IDLE. Here is the quote: "Exercise
(this is just for practice, solutions will not be graded or collected in class)
Use IDLE to calculate:
1.
23.0 to the 5th power
2.
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)
the first one of course went fine but I'm lost on the second one. googled positive root fwiw but that did not help with this situation. help me?
