Answer 1

= (x + 1)^2 − 2

Answer 2

`y=x^2+1`

Explanation:

When simplifying
`y=(x+1)^2` we have to take notice of the square and what it means.

When squaring a number it means multiplying the same number twice for example
`2^2` is 2*2 which is 4.

This is the same for
`(x+1)^2` we multiply
`(x+1)` twice.

So
`(x+1)* (x+1)` is
`x^2 +1`. The 1 stays the same because 1*1 is just one where are x*x is
`x^2`.

So the answer is
`y=x^2+1`
