Answer 1

Verified answer

(x - 2)² (x - 5) > 0
titik uji :
x = 2 dan x = 5

•Utk 2 < x < 5
Misal : x = 3
(3 - 2)²(3 - 5) = 1² . (-2) = -2 < 0 --> tdk memenuhi

• Utk x < 2
Misal : x = 0
(0 - 2)²(0 - 5) = (-2)² . (-5) = -10 < 0 tdk memenuhi

• Utk x > 5
Misal : x = 6
(6 - 2)²(6 - 5) = 4² . 1 = 16 > 0 memenuhi

#yg diminta soal ---> > 0

Maka nilai x yg memenuhi :
x > 5
