tolong bantu aku kerja soal matematika

x²-5x+4=0
(x-1)(x-4)

alpha = 1
beta = 4

alpha - beta = 1-4
= -3

Mapel : Matematika

Bab : Persamaan Kuadrat
_____________, ______

= x² - 5x + 4
= (x - 1)(x - 4)

a > b
→ (x - 1)
x - 1 = 0
x = 1 → nilai b

→ (x - 4)
x - 4 = 0
x = 4 → nilai a

Maka,

= a - b
= 4 - 1
= 3
