When do I resort to using a CAS to solve an equation? Is this one possible by hand?
I got this from a 2 dimensional GPS problem. Here's the math using the distance formula.
L12 = (x1- x)2 + (y1- y)2
L22 = (x2- x)2 + (y2- y)2
I tried the substitution method but it gets nasty and I would have 4th power equations. I don't know if there is a clean answer because Wolfram gave me a very long answer. I also used Wolfram to calculate the numerical answer. Thanks for any help.
