Answer:
[tex]y=x^2+1[/tex]
Step-by-step explanation:
When simplifying [tex]y=(x+1)^2[/tex] 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 [tex]2^2[/tex] is 2*2 which is 4.
This is the same for [tex](x+1)^2[/tex] we multiply [tex](x+1)[/tex] twice.
So [tex](x+1)* (x+1)[/tex] is [tex]x^2 +1[/tex]. The 1 stays the same because 1*1 is just one where are x*x is [tex]x^2[/tex].
So the answer is [tex]y=x^2+1[/tex]
