6x2 + x - 2 কে 2x - 1 দ্বারা ভাগ করলে পাওয়া যায়- 

A 2x + 1

B 3x - 2

C 3x - 1

D 3x + 2

Solution

Correct Answer: Option D

6x2 + x - 2 = 6x2 + 4x - 3x - 2
                  = 2x(3x + 2) - 1(3x + 2)
                  = (3x + 2)(2x - 1)

(6x2 + x - 2)/(2x - 1) = (3x + 2)(2x - 1)/(2x - 1)
                                  = (3x + 2)
