Hey all. I am having trouble factoring a question. If someone could explain how to go about doing this it would be very helpful!
Right, here is the question...
Factor Fully:
a^2 - p^2 +1 +2a
What I've done:
a^2 - p^2 +1 +2a
= (a + p)(a - p) + 1 +2a
unkown how to do the rest.
The answer in the book is: (a + 1 - p)(a + 1 + p). I've checked it and it works out.
Thank you in advanced!
