Question

a^2-2ab+b^2+a+b does this need to be rearranged?

Answer 1

You can complete the square, probably.\[a^2 - 2ab + b^2 \implies (a - b)^2\]

Answer 2

that is not complete the square..

Answer 3

Yeah, that's why I added "probably" at the end. :)

Answer 4

Answer 10

Should this (a^2-2ab+b^2+a+b) be the following:

a^2+2ab+b^2+a+b

Answer 11

@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.
