3x (x^2+6x+9)
3x (x+3). (x+3)
3x. (x+3)^2
The value of the expression will decrease as x increases.
You can test this out by plugging in random numbers in place of x, like 20-5=15 and 20-8=12. The value of the expression (or the answer) is becoming smaller as the value of x becomes larger.
Hope this helps :)
