Question

Simplify.
y = (x + 1)2 -

Answer 1

(x+1)2-

=it is meant to be (x+1)2

=2(x) + 2(1)

= 2x +2

Answer 2

Answer:

Step-by-step explanation:

we can see $y=(x+1)^2$ as y =(x+1)(x+1)

Now to simplify we can use the concept of FOIL and multiply the two parenthesis.

So

$y=(x+1)(x+1)\\y = x^2+x+x+1$

By combining the like terms we get

$y = x^2+2x+1$
