07 – Simplify

What does simplifying mean:

Simplify means collecting the same terms together(like terms)..

Be careful because, ab = a×b and ba = b×a so infact ab = ba.

i.e. 2ab + 3ba = 5ab (or 5ba)

i.e a2b + ba2= 2a2b


Example 1:

Mark out those things that are the same, including their + or – sign, then add or subtract.


Example 2:

In the example below only the ab’s can be added. The other terms are different.


Your Turn:

Simplify the following:

1. 3x + 2y + x – 3y =

2. 3xy2 + 2y + 4xy2=

3. 4x2 + 2x – 5x2 =
