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)
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
4abx - 2axy - 12b2x + 6bxy = (4abx - 2axy) - (12b2x - 6bxy)
= 2ax(2b - y) -6bx(2b - y)
= (2ax - 6bx)(2b - y)
= 2x(a - 3b)(2b - y)
