Solving a quadratic equation by factoring

The video tutorial explains how to solve trinomials by finding their roots or solutions. It introduces the concept of factorization, where a trinomial is expressed as a product of two factors. The zero product property is then used to solve the equations. The process involves creating a tree diagram to identify factors and using these to break down the trinomial. The tutorial also covers verifying solutions by substituting them back into the original equation to ensure they satisfy it.
