### 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. |
