    us a^2 -b^2 =(a-b)(a+b)

    So when I've converted it, it's already factorised?

    I mean, in the given a+2^2 is a^2, same goes with b right? So after I converted it to the other side of the equal sign, will it already be considered as factorised?

    than will be firstly (a+2-(a-3))(a+2+(a-3))

    Yes, but is that the end of the equation? Will that mathematical sentence be considered as "factorised"?

    =((a+2)+(a-3))((a+2)-(a-3))

    Then, it will become -2a+1. Am I correct?
