i am too bad maybe at programming, how do I resolve this?
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 )

maybe start with the Tutorial in the Python documentation ``` >>> >>> 3 * 3 9 >>> 3 ** 2 9 >>> a = 34 >>> b = 68 >>> c = 510 >>> import math >>> math.sqrt(16) 4.0 >>> a * b 2312 >>> a + b 102 >>> (a * b)  c 2822 >>> ```

Well, the equation they are showing is part of the quadratic formula. To find the positive root, you would want to do both parts and see if either of them is positive. Well, in this case, probably just the + one. Knowing that, it is a matter of coding the formula and putting in the givens. Oh, and have it print the result.

Sometimes people don't connect with the videos because they jump in a bit. Try reading the first three chapters of this (only 35 pages): http://www.greenteapress.com/thinkpython/ Try out the code in there. Try other code you think up as you go. Or try the second and third videos here: http://thenewboston.org/list.php?cat=36 If those work well, try up to about video 9, then go back to the MIT stuff, and toss in more of the Bucky videos as you go. Bucky is not bad, but he does not focus on the problem solving aspects you need to learn. However, he makes a great complement to a more formal course of study.
