f(x) = 2x^5 + 3x^4 - 7x^3 + 4x^2 + ax + 6
diket f(x) dibagi (x-2), hasil baginya h(x) dan sisa = 72.
menuruut teoreme sisa ;
f(2) = sisa
2(2)^5 + 3(2)^4 - 7(2)^3 + 4(2)^2 + a(2) + 6 = 72
64 + 48 - 56 + 16 + 2a + 6 = 72
78 + 2a = 72
2a = -6
a = -3
shg,
f(x) = 2x^5 + 3x^4 - 7x^3 + 4x^2 - 3x + 6
Dg mggunkan diagram horner,
hasil baginya h(x) = 2x^4+7x^3+7x^2+18x+33
shg h(x) dibagi (x+1) akan bersisakan :
sisa = h(-1) = 2(-1)^4 + 7(-1)^3 + 7(-1)^2 + 18(-1) + 33 = 17
