Perfect square trinomials allow us to use certain shortcuts in our work with quadratic relationships, so often we try to turn a binomial into a perfect square trinomial by filling in the "c," or constant term. This last constant will always be (b/2) squared . You can always check your work by factoring the trinomial after you have filled in the c term, and making sure you get a binomial multiplied by itself.
