**Reiny**, Sunday, February 27, 2011 at 10:04pmlog3(x^2-4)-log3(x+2)=2

log3 [(x^2-4)/x+2)] = 2

log3 [(x+2)(x-2)/(x+2)] = 2

log3 (x-2) = 2

x-2 = 3^2

x = 11

log3 [(x^2-4)/x+2)] = 2

log3 [(x+2)(x-2)/(x+2)] = 2

log3 (x-2) = 2

x-2 = 3^2

x = 11

You didn't even bother to fix my error in the 2nd line, where I missed a bracket.
