나머지 정리 계산기
나머지 정리를 단계별로 적용하세요
이 계산기는 나머지 정리(베주의 소정리)를 사용하여 $$$f(a)$$$를 계산하며, 단계도 함께 보여줍니다.
Solution
Your input: find $$$f\left(3\right)$$$ for $$$f\left(x\right)=x^{3} - x^{2} + 2 x + 7$$$.
According to the remainder theorem, $$$f(a)$$$ is the remainder from dividing $$$f(x)$$$ by $$$x-a$$$.
Thus, to find $$$f\left(3\right)$$$, find the remainder from dividing $$$x^{3} - x^{2} + 2 x + 7$$$ by $$$x - 3$$$.
For this, use the synthetic division calculator.
The remainder is $$$31$$$, therefore, $$$f\left(3\right)=31$$$.
Answer: $$$f\left(3\right)=31$$$.
