So they gave me this. a^2+2ab+b^2 -x^2-6x-9.
They said " factor the expression. Begin by arranging it as follows.
(1) arrange it with a as variable.
(2) arrange it with b as variable
(3) as a difference of two squares
I understand that they want be to arrange it three different ways and solve and come to the same conclusion because the next page says use any of the three ways. However, when i look at it, I can only see it as a difference of squares. For a bit of context, they were making me do factoring of squared expressions with three terms in the brackets. kinda like (a+b+c)2.
