Brianna Cooke · Answer 1

Answer: x^2 + 4x + 4

Shepherd · Answer 2

x^2 + 4x + 4

Step-by-step explanation:

We can do this first

(x + 2) ^2

Then we can use our knowledge and do

x^2 + 4.

We have to multiple the two by two and then x because that is a rule in

(a + b) ^2

=

a^2 + b^2 + 2ba

So we end up with x^2 + 4x + 4
