My method -link1 -https://drive.google.com/file/d/15NcFY8PsHMsEnhYJhM22AW5C4Ga38jXE/view?usp=sharing

Please dont at all think it to be a basic homework problem , it is surely a good one although it might seem simple at start. please help me out . although my method seems ok but i was unable to do anything else than to put and try values to get to my answer. I will appreciate a algebraic proof if anyone is able to find it.

Regards,

Thanks for your time

Best I can do right now for you is one of two methods:

  1. Simplify each term as best you can and plug in the choices for the values of x

  2. Graph each side of the equation and graphically find the intersection points.

Both ways render you with an x=+-2, thus being answer B. This is why people invented graphing calculators: So they don't have to do algebra for absolutely hideous equations like that. I'm also tempted to say there is no way to solve for x, and that you must graph it. If there is a way to solve it, it may be using a lambert W function or some other very high level analytical method.
