grafik fungsi kuadrat y=5x kuadrat 2 - 13x + 6 memotong sumbu x dititik mohon bantuan nya kak

Bab Fungsi Kuadrat
Matematika SMP Kelas VIII

Memotong sumbu x, maka y = 0

f(x) = 5x² - 13x + 6 = 0
5x² - 13x + 6 = 0
5x² - 10x - 3x + 6 = 0
5x (x - 2) - 3 (x + 2) = 0
(5x - 3) (x - 2) = 0
5x - 3 = 0
x = 3/5

Atau

x - 2 = 0
x = 2

HP = { (2,0), (3/5,0) }
