Factoring Quadratic Expressions Using X and Box

The video tutorial explains how to solve a quadratic equation using the X and Box method. It begins with an example equation, identifies the coefficients, and sets up the X and Box. The tutorial then finds two numbers that multiply to a specific product and add to a specific sum. These numbers are placed in the Box, and the solution is verified by factoring and foiling to ensure correctness.

What are the coefficients a, b, and c in the quadratic expression 2n^2 + 3n - 9?
