log1/3 (x+1) > log3 (2-x)
log3-1 (x+1) > log3 (2-x)
-log3 (x+1) > log3 (2-x)
log3 (2-x) + log3 (x+1)
log3 (2-x)(x+1)
On simplifying the factors and removing log by transposing base of the log to the RHS:
-x2+x+1
x2-x-1 > 0
[x-(1-51/2)/2] [x-(1+51/2)/2] > 0
On Solving the inequality using wavy-curve method:
x belongs to:
(-infinity, (x-(1-51/2))/2) ))/2, +infinity) 1/2x-(1+5 ((
Thank you, hope the solution helps.
