stuck on logarthimic equation
2 log (x+2) + log (x - 1) = 3 log x using a base of 3.
I'm supposed to solve for X. Usually I'm pretty good with these but this I just can't solve. Usually I have to factor, but I keep ending up with a 3rd degree polynomial which my mathbook has not taught me how to solve. So I'm expected to solve it another way. Help! :-(
A logarithm is just a misspelled algorithm.
