E = {x| 2(x-1) = 0}2x - 2 = 0
x = 1
E = {1}
F = {x| x² = 1}
x² = 1
x = 1 atau x = -1
F = {-1, 1}
G = {x| x² - 3x + 2 = 0}
x² - 3x + 2 = 0
(x - 1) (x - 2) = 0
x = 1 atau = 2
G = {1, 2}
=====================================
E = {1}
F = {-1, 1}
Fc = R - {-1, 1} (bil. real kecuali -1 dan 1)
G = {1, 2}
(E n Fc) = R - {-1}
(E n Fc) u G = G
= {1, 2}

Pembahasan:
Himpunan dari:
E = {x | (x-1) 2 = 0}
2x - 2 = 0
2x = 2
x = 1
Maka:
E = {1}
F = {x| x² = 1}
x² = 1
x = 1 , x = -1
Maka:
F = {-1, 1}
G = {x| x² - 3x + 2 = 0}
x² - 3x + 2 = 0
(Pemfaktoran)
(x - 1) (x - 2) = 0
x = 1 , = 2
G = {1, 2}
Maka himpunan yang didapat:
E = {1}
S = { -1, 1}
F = { -1, 1}
= {-1, 1}
G = {1, 2}
(E ∩ ) = { -1, 1}
(E ∩ ) ∪ G = {-1, 1, 2}
