If 2x 2 x - 3 divides x - 2 find the remainder - JAMB Mathematics 2019 Question

If 2x2 + x - 3 divides x - 2, find the remainder.

A

7

B

3

C

5

D

6

correct option: a

By dividing a polynomial p(x) by (x - a), you get a remainder = p(a)

Then for 2x2 + x - 3 ÷ (x - 2), the remainder = p(2).

= 2(2)2 + 2 - 3

= 8 + 2 - 3

= 7.
