1.設f(x)=1250x^6-2790x^5-3125x^4+707x^3+100x^2+45x-62,則f(x)除以x-3的餘式為何?

f(x)=1250x^6-2790x^5-3125x^4+707x^3+100x^2+45x-62
當x-3=0
x=3
f(3)=1250(3)^6-2790(3)^5-3125(3)^4+707(3)^3+100(3)^2+45(3)-62
餘式=f(3)=217

1250+2790-3125+707+100+45- 62|3
…..…3750+2880-735-__84+48+279|
────────────────────────────
1250+_960-_245-_28+_16+93|217
餘式=217
