I think some information is missing (remainder depends on the divisor). First simplify the expression:
3x^3 + x^2 − 2x + 7x + 2 = 3x^3 + x^2 + 5x + 2.
If you mean the remainder when dividing by x − c, use the Remainder Theorem: remainder = f(c). Examples:
- Dividing by x − 1 → remainder = f(1) = 3 + 1 + 5 + 2 = 11.
- Dividing by x + 1 (i.e. x − (−1)) → remainder = f(−1) = −3 + 1 − 5 + 2 = −5.
Tell me the divisor and I’ll give the exact remainder.
