Diketahuiy = x² - 2x + 1
y = -x + 3
jawab
substitusikan kedua persamaan
y = x² - 2x + 1
-x + 3 = x² - 2x + 1
x² - 2x + 1 + x - 3 = 0
x² - x - 2 = 0
(x + 1)(x - 2) = 0
x = -1 atau x = 2
untuk x = -1
y = -x + 3
y = -(-1) + 3
y = 1 + 3
y = 4
untuk x = 2
y = -x + 3
y = -(2) + 3
y = 1
maka hp = {(-1,4),(2,1)}
