Pre-Calculus - Solving a logarithmic equation by using factoring log3(x) + log3(x-8) = 2

The video tutorial explains how to solve a logarithmic equation by applying properties of logarithms, converting to exponential form, and factoring. It highlights the importance of understanding zeros in polynomial functions and identifies extraneous roots. The tutorial emphasizes the need to check solutions by plugging them back into the original equation to determine if they are valid or extraneous.

Why is it impossible to take the logarithm of a negative number?

What is an extraneous root, and how can it be identified?

Discuss the importance of checking solutions in logarithmic equations.
