yang bisa jawab si tolongg

8) |2x - 4| < 6
- 6 < 2x - 4 < 6
- 6 + 4 < 2x < 6 + 4
- 2 < 2x < 10
- 1 < x < 5

9) x² + 10x + 24 = 0
(x + 4)(x + 6) = 0
x = - 4 v x = - 6

1) |2x - 4| < 6.
kasus 1. (2x - 4) > 0
(2x -4) < 6
2x - 4 < 6
2x < 6+4
2x < 10
x < 10/2
x < 5
kasus 2. (2x -4) < 0
-(2x - 4 ) < 6
-2x + 8 < 6
-2x < 6 - 8
-2x < -2
x > 1.
Jadi.HP = { x | 1 < x < 5, x € Real }
