berikut sy menggunakan diagram horner :
(4x³ + 12x² - x - 15) dibagi (x - 1)
setting x - 1 = 0 , diperoleh x = 1
ambil koefesiens seluruh suku yg akan dibagi :
x=1 | (4 12 -1 - 15
|
| 4 16 15
--------------------------------- (+)
4 16 15 0
jadi, hasil baginya = 4x² + 16x + 15 , sisa = 0
caranya harus bertahap
4x³+12x² ÷ x-1 =4x²
4x² × x-1 = 4x³-4x²
⇒ (4x³+12x²)-(4x³-4x²)
= 16x²
⇒16x²-x ÷ x-1 = 16x
16x × x-1 = 16x² -16x
⇒(16x²-x)-(16x²-16x)
= 15x
⇒15x-15 ÷ x-1 = 15
15 × x-1 = 15x-15
⇒(15x-15)-(15x-15)
=0
jadi hasil pembagian 4x³=12x²-x-15 oleh x-1 adalah 4x²+16x+15
