What you will learn in this lesson In this lesson, you will practice simplifying more complicated rational expressions. Let's look at two examples, and then you can try some problems!

Learn how to simplify rational expressions, which are fractions with variable expressions in the numerator and denominator. This video also shows how to factor the expressions and cancel …

Learn what it means to reduce a rational expression to lowest terms, and how it's done!

And so the best way to simplify this, whether we're dealing with expressions in the numerator or denominator, or just numbers, is we want to factor them and see if they have common factors …

In this lesson, you will practice adding and subtracting rational expressions with different denominators. You will use the least common denominator as your common denominator in …

Factor the numerator and the denominator of a rational expression using advanced methods, and cancel out common terms.

This topic covers: - Simplifying rational expressions - Multiplying, dividing, adding, & subtracting rational expressions - Rational equations - Graphing rational functions (including horizontal & …

Rewrite the equivalent form of each rational expression using the common denominator. Add or subtract the numerators of the expressions while retaining the common denominator.

Now let's just simplify the rational expression. We've already said that x cannot be equal to negative 5/2 or negative 6, so let's just divide the numerator and the denominator by 2x plus 5. …

If we start with a simplified rational expression, without any idea of its "original" form, we don't specify any excluded values other than what we see immediately in the simplified form.
