Learn the easy way to simplify a complex fraction by multiplying by the LCD

The video tutorial explains how to solve problems involving fractions by finding a common denominator. The instructor demonstrates factoring to identify the leading coefficient and common denominator, then multiplies each term by the least common denominator (LCD) to eliminate denominators. The process involves simplifying expressions by dividing and adding terms, making the solution straightforward and easy to understand.
