14 - Multiplying, Dividing & Simplifying Rational Expressions, Part 1

In this lesson, you will learn how to work with rational expressions in algebra. We will learn to simplify these types of expressions by fully multiplying the numerator and denominators together, then simplifying the result.

Rational functions consist of the numerator begin a polynomial and the denominator also being a polynomial, so the normal rules of multiplication and division of fractions also apply to rational expressions.

The only difference is that the resulting rational expression must be simplified by canceling terms in order to get the final answer.

Jason is awesome! If students simply do as he explains, this level of algebra becomes easy as pie.

Thank you soooo much for your clear explanation! I'm from the Netherlands and there is no one around who explains this as good as you can in Dutch.

Genius, you always teach us how to think, not just how to calculate like most teacher's did

Hello Mr has an
Kindly could you explain infinite series, sequential circuit and logarithm

[abnerpratt]

Why does that -1 get squared and equation put in ( )?
