himpunan lenyelesaian persamaan X(x-3)+2=0

x(x - 3) + 2 = 0
x^2 - 3x + 2 = 0
x^2 - 2x - x + 2 = 0
x(x - 2) - 1(x - 2) = 0
(x - 1)(x - 2) = 0

Akar akar = 1 dan 2

Hp = { 1 , 2 }

Bab Persamaan Kuadrat
Matematika SMP Kelas VIII

x(x - 3) + 2 = 0
x² - 3x + 2 = 0
(x - 1) (x - 2) = 0
x = 1 atau x = 2

HP = {1, 2}
