Question

simplify y=(x+1)^2-blank

Answer 1

Answer:

$y=x^2+1$

Step-by-step 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 $y=x^2+1$
