Answer

(x+2y)(2c-3d)

Step-by-step solution

4 steps
  1. Group the terms of the expression.

    Group the first two terms and the last two terms. Be careful with the signs when grouping.

    (2cx+4cy)−(3dx+6dy)(2cx + 4cy) - (3dx + 6dy)
  2. Factor out the common factor from each group.

    From the first group, 2cx+4cy2cx + 4cy, the common factor is 2c2c.

    2c(x+2y)2c(x + 2y)

    From the second group, 3dx+6dy3dx + 6dy, the common factor is 3d3d.

    3d(x+2y)3d(x + 2y)
  3. Rewrite the expression using the factored groups.

    2c(x+2y)−3d(x+2y)2c(x + 2y) - 3d(x + 2y)
  4. Factor out the common binomial factor (x+2y)(x + 2y).

    (x+2y)(2c−3d)(x + 2y)(2c - 3d)
