| ×+6 | < ×-5 tolong bantu jwb

*Jika x≥0
x+6 < x-5
    6 < -5

*Jika x<0 
-(x+6) < x-5
-x-6 < x-5
 -2x < 1
    x > -1/2

∴HP={x>-1/2}

I X+6 I < X-5
(x-6)2 < (x-5)2
(x-6).(x-6) < (x-5).(x-5)
x2-12x+36 < x2-10x+25
x2-x2 - 12x + 10x + 36 - 25 < 0
-2x + 11  < 0
-2x < -11
x > 11/2
Jadi HP {x/x<11/2}
NB :
/ = per
2 = pangkat 2
