Calcolatrice del teorema del resto
Applicare il teorema del resto passo dopo passo
La calcolatrice calcolerà f(a) utilizzando il teorema del resto (piccolo teorema di Bézout), con i passaggi indicati.
Solution
Your input: find f(3) for f(x)=x3−x2+2x+7.
According to the remainder theorem, f(a) is the remainder from dividing f(x) by x−a.
Thus, to find f(3), find the remainder from dividing x3−x2+2x+7 by x−3.
For this, use the synthetic division calculator.
The remainder is 31, therefore, f(3)=31.
Answer: f(3)=31.
