- Take out common factors
- Perfect squares (a+b)^2
Difference of 2 squares (b)^2-(a)^2
The main key takeaway today is to recognise which line to use for the equation and to make sure that you will not end up in the “game over” mode. We will have to make sure that we must be able to apply the line in our factorization process.
(sorry for the little notes...)
