1 Method:
Forming a group of first two and the last two terms, we have
(2ax + bx) + (2ay + by)
=> x(2a + b) + y(2a + b)
=> (2a + b) (x + y)
- Sometimes grouping can be done in many ways. In the above example we can form the groups of 2ax, 2ay and bx, by.
2 Method:
(2ax + 2ay) + (bx + by)
=> 2a(x + y) + b(x + y)
=> (2a + b) (x + y)
- We notice that in whatever way the grouping is done, we will always get the same factors.
