Chapter 6 vocab. rational expressions
| Question | Answer |
|---|---|
| Rational Expression | This can be written as the quotient of P/Q of two polynomials P and Q as long as Q is not 0 |
| Opposites | The expression ( x - 8) and (8 - x) are an example of this. |
| Expression | This is written without an equal sign. |
| Equation | This is written with an equal sign |
| Directly | This is the relationship between y and x in the equation y = kx |
| Constant of Variation | The value of k in the equation y = kx |
| Undefined | Is a result when dividing by zero |
| Long Division | To divide a polynomial by a polynomial other than a monomial and can be used when dividing by (3x - 1) as an example. |
| Inversely | In the equation y = k/x, y is said to vary this way with x. |
| Domain | This can be written in the form { x l x is a real number and x is not equal to the number(s) which would make the denominator zero. |
| Complex Fraction | A rational expression whose numerator, denominator, or both contain one or more rational expressions. |
| Least Common Denominator | The _____________ of a list of rational expressions is a polynomial of least degree whose factors include the denominator factors in the list. |
| Jointly | In the equation y = kHz, y varies this way as x and z. |
| Extraneous Solution | It is a proposed solution that makes the denominator zero or does not work in the original equation. |
| Simplified | Reducing to the smallest terms. |
