In order to find the third term in the perfect square trinomial, divide the numerical coefficient of the middle term by 2, then square the answer. In the given perfect square trinomial  x^{2} +2x+_, the numerical coefficient of the middle term is 2, divided by 2 is 1, square the 1 is 1. Therefore, the third term in the perfect square trinomial  x^{2} +2x+_ is 1.
