p = 2/3
Penjelasan dengan langkah-langkah:
px² - 6x + 1 = 0
a = p, b = -6, c = 1
x1 = a
x2 = 2a
x1 + x2 = -b/a
a + 2a = -(-6)/p
3a = 6/p
x1 . x2 = c/a
a . 2a = 1/p
2a² = 1/p
3a = 6(1/p)
3a = 6(2a²)
3a = 12a²
12a² - 3a = 0
3a(a - 3) = 0
a = 0 atau a = 3
a = 0 tidk mungkin jadi yang mungkin a = 3
p = 6/3a
= 2/a
= 2/3
