Answer:
(2x - y)(3b + c + 2d)
Explanation:
Factorize:
From the first two terms 6bx and (-3by) take out the common factor 3b.
From the third and fourth term 2cx and (-cy) take out the common factor c.
From the fifth and sixth term 4dx and (-2dy) take out the common factor 2d.
6bx - 3by + 2cx - cy + 4dx - 2dy = 3b(2x - y) + c(2x - y) + 2d(2x - y)
= (2x - y)(3b + c + 2d)
