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: 2x(a - 3b)(2b - y)
Explanation
4abx - 2axy - 12b2x + 6bxy = (4abx - 2axy) - (12b2x - 6bxy) = 2ax(2b - y) -6bx(2b - y) = (2ax - 6bx)(2b - y) = 2x(a - 3b)(2b - y)
4abx - 2axy - 12b2x + 6bxy = (4abx - 2axy) - (12b2x - 6bxy) = 2ax(2b - y) -6bx(2b - y) = (2ax - 6bx)(2b - y) = 2x(a - 3b)(2b - y)THIS WEEK's
