In this video, the instructor demonstrates how to factor basic trinomials of the form x squared plus bx plus c using the product and sum method. The approach involves identifying two numbers that have a product equal to the constant term of the trinomial and a sum equal to the coefficient of the x term. The instructor walks through several examples, highlighting different methods to find the correct numbers, and reminds viewers to check their work using the FOIL or box method.
This video (part 1) shows a method of factoring a basic trinomial of the form x-squared + bx + c into the product of 2 binomials using the product and sum approach.
