Here's the question you clicked on:

a^2-2ab+b^2+a+b does this need to be rearranged?
You can complete the square, probably.\[a^2 - 2ab + b^2 \implies (a - b)^2\]
that is not complete the square..
Yeah, that's why I added "probably" at the end. :)
lol sorry didnt see that; im tired its called square of a binomial; according to my notes lol
What do we have to do here, @burhan101? :|
i don't know, that's why im asking you guys :(
r we factoring or simplifying here ?
Should this (a^2-2ab+b^2+a+b) be the following: a^2+2ab+b^2+a+b
@burhan101 The reason I asked about the sign is that if the -2ab had been +2ab the expression would have factored as shown on the attached file. As the problem is given, the expression does not factor over the set of rational numbers.
