What is the remainder when 2x² + 1 is divided by x - 1?
- 3
- 2
- 5
- None of these
Explanation
To find the remainder when 2x² + 1 is divided by x - 1:
Use the Remainder Theorem:
Remainder = f(a), where a is the root of the divisor (x - 1 = 0)
a = 1
Substitute a into the polynomial:
Remainder = f(1)
= 2(1)² + 1
= 2 + 1
= 3
