Answer 2

Answer:

6

Step-by-step explanation:

(8x^3)-1/ 6x^2-5x+1                   [(8x^3)-1 can be written in a^3-b^3 form]

(2x^3)-1^3/ (2x-1)(3x-1)                 [6x^2-5x+1 is factorized into (2x-1)(3x-1)]

(2x-1)(4x^2+1+2x)/ (2x-1)(3x-1)       [(2x-1) can be cancelled out]

4x^2+2x+1/ 3x-1                          [substitute 1/2 in place of x]
