2log(x-1) + logx = logx + log4

What are you doing?
6/2=3 and 2-2=0.
Your both the answers are wrong. Correct them.

OMG, such simple mistakes huh, ok

x= 6/2 = 3

x= -(-2) - 2/ 2 = 0/2 x= 0

That's too much unnecessary work. From,

$$(x-1)^2=4$$

Take the square root of both sides (remember the $\pm$).

You're right Mentallic but nae99 is doing such silly mistakes here in this thread.

@nae99- take care, since you need to consider this case:- x-1>0

thanks much
