Ultimately, the trinomial should be factored in the form
Some trinomials, known as perfect square trinomials, can be factored into two equal binomials. For example:
Perfect square trinomials always factor as the square of a binomial.
To recognize a perfect square trinomial, look for the following features:
- The first and last terms are perfect squares.
- The middle term is divisible by 2.
Given that the coefficient of x2 is 1, we know that the factored form will be
