# Question #bd0e0

##### 1 Answer

You can't. This expression is unfactorable.

#### Explanation:

A perfect square trinomial is a trinomial (a polynomial with three terms) that can be factored down into one of two forms:

1)

or

2)

If we expand both of those out, we get

1)

and

2)

Let's see if

The two terms are perfect squares! Now let's see - the middle term has to be twice the product of the two squares.

Our two squares are

Nope. Let's try the other combination:

Nope either. Even though our first and last terms were perfect squares, the middle term did not have the properties of a perfect square trinomial.

Therefore, *not* a perfect square trinomial. And so, it cannot be expressed as the product of two binomials.
