1. Tentukan akar-akar persamaan kuadrat berikut : a. x2 – 5x – 24 = 0 b. 9x2 – 12x + 4 = 0 c. x2 – 4x + 1 = 0 tolong yah thankyou :))

Persamaan Kuadrat
Kelas X

a. x² - 5x - 24 = 0
x² + 3x - 8x - 24 = 0
x(x + 3) - 8(x + 3) = 0
(x + 3)(x - 8) = 0
x = -3 / x = 8

b. 9x² - 12x + 4 = 0
(3x - 2)² = 0
3x - 2 = 0
3x = 2
x = ⅔

c. x² - 4x + 1 = 0
x² - 4x = -1
x² - 4x + 4 = -1 + 4
(x - 2)² = 3
x - 2 = ±√3
x = ±√3 + 2

x = √3 + 2 atau x = -√3 + 2
