Verified answer
|3x + 7| ≤ |2x - 5|(3x + 7)² - (2x - 5)² ≤ 0
▶ A² - B² = (A + B)(A - B)
(3x + 2)(x + 12) ≤ 0
-12 ≤ x ≤ -2/3
Opsi : C
(3x+7+2x-5) (3x+7-2x+5)
(5x+2) (x+12)
5x+2=0 x+12=0
5x=-2 x=-12
x=-2/5
hp= {x|-12<_x<_ -2/5}
mungkin jawaban dibukunya salah atau jawaban sya yg slh.. sya ga tau jga.. sya cuma bisa bantu segitu
