suku banyak
sisa bagi =  nilai  fungsi
s(x) = f(x)

Penjelasan dengan langkah-langkah:

jika suku banyak x³ + 2x²-5ax-7 dibagi x + 1 sisanya R₁.
R₁ = x³ + 2x²-5ax-7
x + 1 = 0
x = -1
R₁ = (-1)³ + 2(-1)² - 5a(-1) -  7
R₁ =  -1 + 2 + 5a -  7
R₁ =  5a - 6

Jika sukubanyak 3 x³ + ax²-12x + 6 dibagi x-2 sisanya R₂.
R₂ = 3 x³ + ax²-12x + 6
x - 2 =  0
x = 2
R₂ = 3 x³ + ax²-12x + 6
R₂ = 3 (2)³ + a(2)²- 12(2) + 6
R₂ = 24 +  a(4) -  24 + 6
R₂ = 4a + 6

2R₁ + R₂  = 6
2(5a-6)  +  4a + 6 =  6
10a - 12 +  4a +  6 =  6
14 a -  6 =  6
14a = 12
a =  12/14
a = 6/7
