ax + 2ay + bx + 2by
= ax + bx + 2ay + 2by
= (ax + bx) + (2ay + 2by)
= x(a + b) + 2y(a + b)
= (a + b)(x + 2y)

ax + 2ay + bx + 2by.

First, group the first two terms and the last two terms.
(ax + 2ay) + (bx + 2by).
a (x + 2y) + b (x + 2y).
= (x + 2y) (a + b).

The answer to the problem is (x + 2y) (a + b).

ax + 2ay + bx + 2by
= a(x + 2y) + b(x + 2y)
now factor out (x + 2y)
= (x + 2y ) (a + b)

ax + 2ay + bx + 2by = a(x+2y) + b(x+2y)
= (a+b)(x+2y).

a(x+2y)+b(x+2y)=(x+2y)(a+b)
