We have to solve: log(3x + 5) (9x*x + 8*x +2) >
2
log(3x + 5) (9x*x + 8*x +2) >
2
=> 9x*x + 8*x +2 > (3x +
5)^2
=> 9x^2 + 8x + 2 > 9x^2 + 30x +
25
=> 8x - 30x > 25 -
2
=> -22x >
23
=> x <
-23/22
But the base of the logarithm has to be greater than
0
=> 3x + 5 >
0
=> x >
-5/3
The solution of the inequality is -5/3
< x < -23/22
