p-2 ≠ 0 dan p+2≠0
p ≠ 2 p ≠ -2
cari akar2 pers P
akar persamaan 5p-2 = 0
5p = 2
p = 2/5
batasan2 garis bilangan
_____-2_______2/5____2____
jika p = -3
jika p = -1
jika p = 1
jika p = 3
------- -2 ++++ 2/5 ------2 +++++
karena tanda < 0 , ambil yang negatif
p < -2 dan 2/5 < p < 2 dan p ≠ 0
yang memenuhi jawaban p < -2 dan 2/5 < p < 2 dgn p ≠ 0
