tolong bantuannya ya kaak. soalnya besok mau UKK. 1. dengan cara memfaktorkan carilah akar akar persamaan kuadrat a. X2 + 10X + 16 = 0 b. X2 + 8X + 15 = 0 c. 3X

Nomor A :
x² + 10x + 16 = 0
x² + 2x + 8x + 16 = 0
x (x + 2) + 8 (x + 2) = 0
(x + 2) (x + 8) = 0
x1 = -2, x2 = -8

Nomor B :
x² + 8x + 15 = 0
x² + 3x + 5x + 15 = 0
x (x + 3) + 5 (x + 3) = 0
(x + 3) (x + 5) = 0
x1 = -3, x2 = -5

Nomor C :
3x² - 2x - 8 = 0
(3x + 4) (x - 2) = 0
x1 = -4/3, x2 = 2
