Simplify Rational Expressions in Algebra (Step-by-Step)

Are you ready to master simplifying rational expressions? 📚 This beginner-friendly algebra tutorial breaks down the process of reducing algebraic fractions into their lowest terms. We'll guide you through the essential 4-step method: factoring the numerator, factoring the denominator, identifying common factors, and canceling them out to find the simplified answer.

Learn the core concepts behind rational expressions and see how they're just like the fractions you're already familiar with. We'll work through clear, step-by-step examples, from simple binomials to more complex trinomials. Plus, we'll cover the critical topic of 'excluded values' to ensure your answers are always mathematically correct. You'll also learn to avoid the most common mistake students make: canceling terms instead of factors. By the end of this video, you'll have the confidence to tackle any rational expression! ✨
