Learn how to subtract two rational equations when the denominators are trinomials

The video tutorial covers the process of dealing with rational expressions, focusing on factoring techniques. The instructor demonstrates how to factor expressions mentally and checks the work for accuracy. The lesson progresses to finding the least common multiple (LCM) to combine fractions with different denominators. The tutorial concludes with a reminder to practice these skills and a brief mention of further steps to be shown off-video.
