Solve the logarithmic equation algebraically and approximate the result
Ln x + Ln(x - 2) = 1
I solved it to approximately 2.928
I want to ask why the negative number is extraneous because I'm having a difficult time grasping what is going on with the 2 variables being found on the graph, and graphing it wise. Seriously...why are negative answers extraneous???
Thanks in advance!
