Hi all, How can I solve this? I tried with log_a (b) - log_a (c) = log_a (b/c) but the solution is (13+5x)/(x^2+5x+4)>=0 ...how is this possible? Thanks in advance

Okay, as you say, is the same as . Further , for any a< 1, if and only if . That is, your inequality is the same as . Subtracting 1 from both sides, . Now, multiply both sides by -1.
