Using factoring to help us determine the LCD and solve a rational expression

The video tutorial explains how to factor trinomials and the importance of finding the least common denominator (LCD) to eliminate fractions in equations. It guides students through solving equations without fractions and emphasizes the need to check solutions to ensure they do not violate any constraints, such as making the denominator zero.

What is the first step to take when trying to factor a trinomial?

Explain the process of eliminating fractions when solving an equation.

What does LCD stand for and why is it important in solving equations?

How do you check if your solution to an equation is valid?

What are the constraints that must be considered when solving equations involving fractions?
