dengan metode kuadrat sempurna
bantuuu butuh bgtt
Penjelasan dengan langkah-langkah:
x² - 5x - 14 = 0
x² - 5x = 14
(x - 5/2)² - 25/4 = 14
(x - 5/2)² = 14 + 25/4
(x - 5/2)² = 56/4 + 25/4
(x - 5/2)² = 81/4
x - 5/2 = ±√81/4
x - 5/2 = ±9/2
x = 5/2 ± 9/2
x1 = 5/2 + 9/2 = 14/2 = 7
x2 = 5/2 - 9/2 = -4/2 = -2
Hp = {7,-2}
