Answer:
(x+2)^2
Step-by-step explanation:
x^2+4x+2^2
Simplify!!!
x^2 + 4x +4
2^2 is also know as squaring when a number is multiplied by itself, 2 x 2
Now time to factor, what you need to look at is the last two numbers and ask...
What two numbers add to give me 4 and multiply to give me 4
We look at the factors of 4: 1,2,2,4
As you can tell 1 and 4 definitely don't work because 1+4=5 or 1-4= -3 and so forth
Therefore 2,2 are the numbers we need!! Lets check just in case
2 +2 gives us 4 or 4x in this case
and 2 x 2 gives 4
Therefore when you factor you place the equation in factored form
(x+2)^2
