Faktorkanlah A. 2a^2-2 B. 12x^2-27 C.18x^2-32y^2 D. 24m^2-54n^2 E. x^2-3 Pakai cara

a)
2a² - 2
= 2(a² - 1)
= 2(a + 1)(a - 1)

b)
12x² - 27
=3(4x² - 9)
= 3(2x + 3)(2x - 3)

c)
18x² - 32y²
= 2(9x² - 16y²)
= 2(3x + 4y)(3x - 4y)

d)
24m² - 54n²
6(4m² - 9n²)
6(2m + 3n)(2m - 3n)

e)
Tidak dapat difaktorkan

ingat :
a² - b²
= (a + b)(a - b)

2a^2 - 2 = 0
a^2 - 1 = 0
(a - 1)(a + 1)

b.) 12x^2 - 27 = 0
4x^2 - 9 = 0
(2x + 3)( 2x - 3)

c.)
18x^2 - 32y^2 =
2(3x - 4y)^2

d.)
24m^2 - 54n^2 =
6(2m - 3n)^2

e.) x^2 - 3 =

x^2 - 3
