Factorize 62x + 1 + 7(6x) – 5
-
A.
[3(6x) – 5][2(6x)m + 1] -
B.
[3(6x) + 5][2(6x) – 1] -
C.
[(6x) – 5][3(6x) + 1] -
D.
[2(6x) + 5][3(6x) – 1]
Correct Answer: Option B
Explanation
62x + 1 + 7(6x) – 5
Let 6x = y….(i)
6yx + 7y – 5 = 0
(3y + 5)(2y – 1) = 0…..(i)
Subt. for y from eqn. (i) in eqn. (ii)
= [3(6x) + 5][2(6x) – 1]
