Solve this problem.........

Please note down your answer and compare my answers.

3.















Answer:
1.( x + y ) 2
What we call this "expand" so just expand it.

2. 16 or 6 how come?????
you try to look another way, i/n can cut with another n so it become 1 six= 16 or just six

I said find x(where is x), so just circle it or just tell note down, because i did not say find the VALUE of x.
