Factorize completely 4abx – 2axy -12b2x + 6bxy
-
A.
2x(a – 3b)(2b – y) -
B.
2x(3b – a)(2b – y) -
C.
2x(a – 3b)(y – 2b) -
D.
2x(2b – a)(3b – y)
Correct Answer: Option A
Explanation
4abx – 2axy – 12b2x + 6bxy = (4abx – 2axy) – (12b2x – 6bxy)
= 2ax(2b – y) -6bx(2b – y)
= (2ax – 6bx)(2b – y)
= 2x(a – 3b)(2b – y)
