a = (x + 2)log4

2logx . (x + 2)log4 < 2 - (x + 2)log4
2logx . a < 2 - a
a . 2logx + a < 2
a (2logx + 1) < 2
(x + 2)log4 (2logx + 2log2) < 2
(x + 2)log2^2 (2log2x) < 2
2 . (x + 2)log2 . 2log2x < 2
(x + 2)log2 . 2log2x < 2/2
(x + 2)log2x < 1
(x + 2)log2x < (x + 2)log(x + 2)
2x < x + 2
x < 2

Syarat
2logx ==> x > 0
(x + 2)log4 ===> (x + 2) > 0 => x > -2

x < 2 : xxxxxxxxxxxxxxxx (2) .............
x > 0 : ................. (0) xxxxxxxxxxxxxx
x > -2 : .... (-2) xxxxxxxxxxxxxxxxxxx
HP = 0 < x < 2
