( 3a + 2b )
---------------- x
2b dikali 2b = 4b^2
2b dikali 3a = 6ab
3a dikali 2b = 6ab
3a dikali 3a = 9a^2
maka hasilnya adalah
---------------------------------------- X
2b dikali 9a^2 =
2b dikali 12ab = b^2[/tex]
2b dikali 4b^2 =
3a dikali 9a^2 =
3a dikali 12ab =
3a dikali 4b^2 =
maka hasilnya adalah
=((3a+2b)(3a+2b))(3a+2b)
=(3a(3a+2b)+2b(3a+2b))(3a+2b)
=(9a²+6ab+6ab+4b²)(3a+2b)
=(9a²+12ab+4b²)(3a+2b)
=9a²(3a+2b)+12ab(3a+2b)+4b²(3a+2b)
=27a³+18a²b+36a²b+24ab²+12b²a+8b³
=27a³+54a²b+24ab²+12b²+8b³
