Question

[(x-3)+y] [(x-3)+y]

I got two answers for these problems which one is correct?
x^2 - 6x +y^2

and

x^2 -6x +9 + 2xy + y^2

Answer 1

both will be correct. coz it seems like quadratic equation dear.

Answer 2

\[\Large [(x-3)+y]\cdot [(x-3)+y]=(x-3+y)\cdot (x-3+y)\]

\[\Large x^2-3x+xy-3x+9-3y+xy-3y+y^2\]

\[\Large x^2-6x-6y+2xy+9+y^2\]

Answer 3

@Kreshnik
how you magnify your equations? when you write equation then it becomes large font. how?

Answer 4

\[\huge x^2-4+23...\] --- this one was \huge then write equation...

I write mostly with .. \Large ... BUT sometimes \LARGE

THE ONE YOU ASKED WAS TYPED WITH \Large :)

Answer 5

neither of your answer is correct. @Kreshnik's answer is the right answer.
