Question

Factor.

x^2 4x +4

(x + 2)^2

(x+4)^2

(2 – 2)^2

(2 – 4)^2

Answer 1

Answer: The answer is
`(x+2)^2`

Explanation:

Because
`(x+2)^2` means
`(x+2)(x+2)`

So we use the foil method to factor

First:
`x*x=x^2`

Outside:
`x*2=2x`

Inside:
`2*x=2x`

Last:
`2*2=4`

So we now write the following equation
`x^2+2x+2x+4`

Simplfied
`x^2+4x+4`
