This document provides instructions on how to factor trinomials into two binomials. It gives the example of factoring 3x^2+5x+2. The steps shown are to identify the greatest common factor of the coefficients and factor the trinomial accordingly. The factored form is (3x+2)(x+1). To check the work, the factored binomials are multiplied out, correctly yielding the original trinomial 3x^2+5x+2.
