toling di bantu buat besok sekalian jalan nya kalok gk bisa jawab gua di hukum tolong bang kakak bantu plisss

3x²-x-15 = 0 misal a = 3, b = -1, c = -15
p+q = -b/a = -(-1)/3 = 1/3
p×q = c/a = -15/3 = -5
p²+q² = (p+q)²-2×p×q = (-b/a)² -2c/a = (1/3)² - 2 × -5 = 1/9 + 10 = 91/9

p/q + q/p = p² + q² / p×q = 91/9 / -5 = 91/9 × -1/5 = -91/45 = -2 ¹/45 (B)
