What is the remainder when 2x^3 - x^2 + 5x + 2 is divided by (x - 1)?
Answer and explanation
Correct answer: A. 8
- Step 1: By the remainder theorem, the remainder on division by (x - a) is f(a).
- Step 2: f(1) = 8.
Answer
8.
Why not the others: -6 evaluates at -1 instead of 1; 2 is the constant term.
