A.(a - 2b)(x + 3y)
B.(a + 2b)(x - 3y)
C.(a + 3b)(x - 2y)
D.(a - 3b)(x + 2y)

Answer 1

Group the first two terms and factor out a.
Group the last two terms and factor out 3b.
Then you will have two terms with the common factor x-2y. Factor it out.

Answer 2

Or you could use FOIL on each answer until you find the one that gives you the original expression.
