Study Notes
Rational Expressions
- Rational expression refers to a fraction formed by the ratio of two polynomial expressions.
Simplification
- The process of simplifying involves writing a fraction or expression in its simplest or most concise form, making it easier to work with.
Multiplication of Rational Expressions
- To multiply two rational expressions, use the formula: ( \frac{a}{b} \times \frac{c}{d} = \frac{ac}{bd} ) where ( b ) and ( d ) must not equal zero to avoid undefined expressions.
Division of Rational Expressions
- Dividing rational expressions follows this process: ( \frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c} = \frac{ad}{bc} ), ensuring that ( b ), ( c ), and ( d ) are not zero.
Greatest Common Factor (GCF)
- The GCF is defined as the largest number that can evenly divide all numbers in a given set without leaving a remainder. For instance, the GCF of 8 and 12 is 4.
Factors
- A factor is any number that can be multiplied by another number to yield a specific product, playing a crucial role in simplifying expressions and finding GCF.
Reiteration of Simplification
- The term "simplify" has been highlighted again, emphasizing the need for writing a fraction or expression in its simplest form for clarity and ease of use.
