Answer:

(

x

2

)

(

x

2

)

=

0

x

=

2

Step-by-step explanation:

To factor the expression you need to find factors of 4 which add up to 4.

The signs will be the same (because of +4), they are both minus (because of -4x).

2

×

2

=

4

and

2

+

2

=

4

(

x

2

)

(

x

2

)

=

0

Now that we have the factors, we can solve:

If

x

2

=

0

, then

x

=

2

(Sorry if confusing, it wouldnt let me write it out how i wanted to..)
