# Quadratics

### stack of terms and definitions

Term | Definition |
---|---|

axis of symmetry | negative b over two a |

quadratic equations | are quadratic functions that are set equal to a value |

standard form | ax squared plus bx plus c equals 0 |

roots | solutions of a quadratic equation |

zeroes | method for finding the roots of a quadratic equation |

zero product property | for any real numbers a and b, if ab equals zero then either a =0, b=0 or both a and b equal 0 |

complex numbers | any number that can be written in the form a plus bi, where a and b are real numbers and i is the imaginary unit.a is called the real part and b is called the imaginary part |

completing the square | quadratic equations can be solved using the square root property by manipulating the equation until one side is a perfect square |

graphing | solves quadratic equations |

domain | what the solution will have |

x-intercept | where the graph crosses over the x-axis |

y-intercept | where the graph crosses over the y-axis |

square root property | find solutions using the square root method |

quadratic formula | can be used to solve any quadratic equation. the formula can be derived by solving the standard form of a quadratic equation |

discriminant | the value of the discriminant can be used to determine the number and type of roots of a quadratic equation |

difference of two squares | subtracting two square roots to find a solution |

graphing | using a calculator to graph and find the solution |

maximum | highest point |

minimum | lowest point |

parabola | graph of a formula of a quadratic |
