How to find the LCD to add two rational expressions

The video tutorial reviews simplification from the last class, focusing on factoring trinomials and finding two numbers that multiply to a given product and add to a given sum. It explains the concept of the least common denominator (LCD) and how to find it. The tutorial also covers applying the distributive property to expressions and combining terms to reach a final answer.

What are the steps to combine terms in the numerator after applying the distributive property?

What could the final answer look like when simplifying the expression given in the lesson?
