Complete the square for the expression, then factor the trinomial. x^2-4x

please explain how to do it as well! :)

Completing the square we get:

and factoring the term we get:

Step-by-step explanation:

We need to complete the square for the expression

For completing the square the expression would be of form

For given expression we have to add (2)^2 and subtract to make it complete the square.

Now, we have to factor the polynomial using formula

So,

Completing the square we get:

and factoring the term we get:
