How to Simplify a complex fraction by multiplying by the LCD

The video tutorial covers the concept of domain restrictions in mathematical expressions, focusing on identifying values that make denominators zero, which are undefined. It explains how complex numbers do not affect domain restrictions. The tutorial then demonstrates simplifying expressions by identifying and using the least common denominator (LCD) and checking for any additional constraints. The final answer highlights the domain restrictions as specific values that cannot be included.
