Learn how to factor a trinomial using the diamond method

The video tutorial explains how to factor trinomials using the diamond method. It begins with an introduction to the standard form of a quadratic equation and then describes the diamond method, which involves finding two numbers that multiply to give the constant term and add to give the linear coefficient. The tutorial provides a step-by-step guide to applying this method, including identifying the correct factors and writing the trinomial as a product of its factors.
