tolong yaa please.. mau di kumpul sekarang..

A.)
(x - 2)^(x² - 2) = (x - 2)^x

P1
x² - 2 = x
x² - x - 2 = 0
(x + 1)(x - 2) = 0
x = -1 --- x = 2

P2
x - 2 = 0
x = 2

P3
x - 2 = -1
x = 1

syarat genap atau ganjil
x² - 2 = x ------ (x = 1)
1 - 2 = 1
-1 = 1 (memenuhi karena sama" ganjil)

P4
x - 2 = 1
x = 3

HP{-1, 1, 2, 3}


B.)
x² - 4x + 12 = x - 2
x² - 5x + 14 = 0

HP{ }

semoga membantu...
