### How to factor perfect square trinomials?

There are three sets of factoring perfect square trinomial worksheets.

• Factor Perfect Square Trinomials.
• Factor Perfect Square Trinomials (GCF).
• Factor Perfect Square Trinomials (two variables).

A perfect square trinomial is a trinomial expression that can be factored into the square of a binomial. The general form of a perfect square trinomial is a² + 2ab + b², where a and b are any real numbers.

To factor a perfect square trinomial, you can follow these steps:

1. Identify the perfect squares in the expression.
2. Confirm that the middle term is twice the product of ab.
3. Write the factored form as (a + b)².

Example: Factor the expression x² + 6x + 9

1. Identify the perfect squares. In this case, the perfect squares are x² and 3².
2. Confirm that the middle term is twice the product of ab: 6x = 2(3x).
3. Write the factored form as (x + 3)².

However, not all trinomial expressions are perfect square trinomials. For example, the expression x² + 10x + 25 is not a perfect square trinomial because the middle term is not twice the product of ab.
