Answer 2

Remember

perfect squares are

(x+y)(x+y)

or (x-y)(x-y)

so both have to be the same thing multiplied by itself

Answer 3

thank you

Answer 4

you're welcome

also don't get confused

if they write it as (x+y)(y+x) - it's still a perfect square

because it's the same thing

(y+x) is the same thing as (x+y)

so it's still (x+y)(x+y)
