In this lesson we are going to learn how to factor trinomials with a coefficient of 1 for the squared term. When factoring a trinomial, always begin by looking for a greatest common factor first. We used the FOIL method to multiply two binomials together. Some trinomials can be factored by using the FOIL process in reverse. This lesson also covers some tips when using the reverse FOIL. For example, if the middle and the last term in the trinomial are positive, then your two last terms of the binomials must also be positive.
