Question

please tell me questions number second ​

Answer 1

The following question is of the form (a+b+c)², It means you have to simplify this to it's simplest form , it is in the answer form.

Answer

When simplified we get,

(-√2x)² + (y)²+ (2√2)²+ 2(√2x)(y) + 2(y)(2√2) +2(√2) (2√2)

So finally we need to put it in the form (a+b+c)²

When we do so we get ,

(-√2x+y+2√2)²

Which is the answer obtained and is the answer to your question my friend
