Thank you so much! I had the variables right, I was putting the denominator underneath the sq. root sign, which of course would throw everything off. I knew it had to be a simple math mistake. Thank you for your help!

Ok, I'm not sure what I'm doing wrong. Using 2x^2 - 8x + 8: 8 +- sq.root((8^2 - 4(2)(8))/2(2)) gives me +- 8. ? I even tried to plug it into a quadratic formula calculator online, and that gave me 2 for both x's. I just don't understand. Would switching the denominators give me a...

Thanks! I knew I was probably making a basic math problem. So this is the new reworked ending, which still doesn't seem to work out. 2x^2 + 8x - 8 = 0. Plugging this into the quadratic gives me 2.35 and 13.65, both of which are obviously not even close to 1.17, nor are they even in the...

[b]1. Here is the question we were given: There are two charges on a horizontal line of 2 m length. *-----------------------* Qa = +4q Qb = +2q If a third point of charge "q" is moved between these points, where will the forces acting...
