I am working on a physics problem from a calc-based E&M (intro) course, and I came up with the following equation:
E = 0 = 10 / (1 - x)2 + 5 / x2 - 10 / (1 + x)2
I got here and worried it was a dead end, so I checked the solutions manual, and they have the exact same thing, and then say " therefore, the root is bla. So, ~equation~ = 0 => x = bla"
How did they solve this? =|
edit: The only attempt I would know how to make is solve one of the terms individually, and then solve the other two as a system, and hope that one of the two solutions coincide. However, this seems stupid because that basically leaves it all to chance.
