Find the number to add to to make it a perfect square trinomial. write that trinomial as the square of a binomial?

Divide the b parameter by 2 and rewrite it as the square of a binomial inserting the x, and the c as the half of b.

.

Step-by-step explanation:

1) Every perfect square trinomial can be written as the square of a binomial. For instance:

2) Firstly let's complete the square

2a. Find "c", the constant term by dividing "b"

2b. Square it

3) Since we completed the square, then to write that trinomial as the square of a binomial :

Divide the b parameter by 2 and rewrite it as the square of a binomial inserting the x, and the c as the half of b.
