Solving a quadratic equation for a variable

The video tutorial explains how to solve a literal equation to find the variable A. It begins by introducing the concept of literal equations, which do not contain numbers, making them challenging. The instructor demonstrates how to isolate A by undoing operations such as addition and multiplication. The process involves subtracting terms and dividing by X squared to solve for A, resulting in the equation A = (Y - BX - C) / X^2.
