Materi : Program LinearBahasan : Pertidaksamaan Linear
Jawaban : HP = {x | x < - 4 ∨ x > 4, x ∈ R}
Langkah - langkah :
x² - 10 > 6
⇔ x² - 10 - 6 > 0
x² - 16 > 0
Faktorisasi ;
(x + 4) (x - 4) > 0
x = - 4 atau x = 4
Garis Bilangan dan Intervalnya :
++++ (- 4) ------ (4) +++++
Karena diminta x > 0 (positif), maka :
HP = {x | x < - 4 ∨ x > 4, x ∈ R}
