You can put this solution on YOUR website! I have tried but i cannot solve this equation, I would appreciate some help, pls
log(x+1)^2 + log(x+9)^2 = 2log9
-----------
Assuming it's log( (x+1)^2) and not the log^2:
-----
2log(x+1) + 2log(x+9) = 2log9
log(x+1) + log(x+9) = log(9)
log((x+1)*(x+9) = log(9)
x = 0, x = -10
-----
-10 won't work, so ignore it.
--> x = 0
