Penjelasan dengan langkah-langkah:a = 6, d = 2 -> d = a/3c = 9, a = 6 -> c = 3a/2
9a + 6b + 8c + d²= 9a + 6b + 8(3a/2) + (a/3)²= 9a + 6b + 24a/2 + (a²/(3²))= 9a + 6b + 12a + (a²/9)= 6b + (9 + 12 + (a/9))a= 6b + (21 + (a/9))akarena a = 6, maka= 6b + 6(21 + (6/9))= 6(b + 21 + (6/9))= 6(7 + 21 + (6/9))= 6(28 + (6/9))= 6(28 + (2/3))= 6((84/3) + (2/3))= 6(86/3)= 2(86)= 172

= 172
Penjelasan dengan langkah-langkah:
a = 6, d = 2 -> d = a/3
c = 9, a = 6 -> c = 3a/2
9a + 6b + 8c + d²
= 9a + 6b + 8(3a/2) + (a/3)²
= 9a + 6b + 24a/2 + (a²/(3²))
= 9a + 6b + 12a + (a²/9)
= 6b + (9 + 12 + (a/9))a
= 6b + (21 + (a/9))a
karena a = 6, maka
= 6b + 6(21 + (6/9))
= 6(b + 21 + (6/9))
= 6(7 + 21 + (6/9))
= 6(28 + (6/9))
= 6(28 + (2/3))
= 6((84/3) + (2/3))
= 6(86/3)
= 2(86)
= 172
