(x - d)^2 + x - d
The answer, according to the book, is: (x-d)(x-d+1)
I am unsure how to go about doing this problem at all. I have been searching around different math sites for about an hour now trying to find this type of problem, but as I am unsure how to categorise it besides "factoring", I got little results.
