It's important to recognize the form of perfect square trinomials so that we can easily factor them without going through the steps of factoring trinomials, which can … Perfect Squares. When you learn to factor quadratics, there are three other formulas that they usually introduce at the same time.The first is the "difference of squares" formula. (Notice the subtraction sign between the terms.) Recall that a difference of squares can be rewritten as factors containing the same terms but opposite signs because the middle terms cancel each other out when the two factors are multiplied.
