Bab Persamaan KuadratMatematika SMA Kelas X
y = y
x² - x + 1 = 2x + 1
x² - x - 2x + 1 - 1 = 0
x² - 3x = 0
x (x - 3) = 0
x = 0 atau x - 3 = 0
x = 3
y = 2x + 1
= 2 . 0 + 1
= 1
y = 2x + 1
= 2 . 3 + 1
= 7
Koordinat titik potong = { (0,1), (3, 7) }

Perpotongan Grafik.2x + 1 = x² - x + 1
x² - 3x = 0
x(x - 3) = 0
x = 0 ∨ x = 3
Untuk x = 0
y = 2(0) + 1 = 1
Untuk x = 3
y = 2(3) + 1 = 7
Titik potongnya (0, 1) dan (3, 7).
