Tolong bantu mencari hp nya yg soal bawah

Answer 1

Verified answer

Y = x² - 2x + 1
2 = x - y --> y = x - 2

y = y
x² - 2x + 1 = x - 2
x² - 2x + 1 - x + 2 = 0
x² - 3x + 3 = 0

Cek nilai Diskriminan (D)
D = b² - 4ac
D = (-3)² - 4.1.3
D = 9 - 12
D = -3

D < 0

rumus abc
x1.2 = (-b ± √(b² - 4ac))/2a
x1.2 = (3 ± √-3)/2
x1.2 = (3 ± i√3)/2

x1 = 3/2 + 1/2 i√3 ---> y1 = x + 2 = 7/2 + 1/2 i√3

x2 = 3/2 - 1/2 i√3 ---> y2 = 7/2 - 1/2 i√3

HP = {(x1,y1) , (x2,y2)}
