|4x+5|<2 jawabannya apa ya teman teman???

|4x + 5| < 2
(4x + 5)^2 < 2^2
(4x + 5)^2 - 2^2 < 0
(4x + 5 + 2)(4x + 5 - 2) < 0
(4x + 7)(4x + 3) < 0
x = -7/4 atau x = -3/4
Garis bilangan
+++ (-7/4) --- (-3/4) ++++
-7/4 < x < -3/4

Cara lain
|4x + 5| < 2
-2 < 4x + 5 < 2
-2 - 5 < 4x + 5 - 5 < 2 - 5
-7 < 4x < -3
-7/4 < 4x/4 < -3/4
-7/4 < x < -3/4

x<-0.75 ini betul apa gk ya
