i really need help with some factoring!!
ive been working on these 2 problems foreverrr!!!!!!!!!!
(x+a)^2 - 2(x+a) (y+a) + (y+a)^2
For the first problem,
try a change of variables to maybe simplify things
let then rewriting the equation results in
now replacing what we defined as u and v we get
For the second problem
using the same technique let
rewriting the equation will result in
factor this expression and back substitute for u and v
Hope this helps
