# Quadratics

Quadratic Formula | -b(+)(-)square root of b^2 + 4(a)(c) divided by 2a |

Discriminant | b^2-4ac |

Completing the Square | All quadratic equations can be solved by using the Square Root Property by manipulating the equation until one side is a perfect square |

Imaginary Unit i | defined to be: i^2=-1 |

Pure Imaginary Number | square roots of negative real numbers |

Square Root Property | the sum of squares can be factored over the complex numbers |

Complex Number | terms are not like terms and cannot be combined |

Complex Conjugates | two complex numbers in the form of a+bi and a-bi |

Factored Form | 0=a(x-p)(x-q) |

FOIL Method | use this method to write a quadratic equation that is in factored form, in standard form; uses the distributive property |

Quadratic Equation | equations that are set equal to a value |

Standard Form | ax^2+bx+c=0 |

Roots | Solutions of a quadratic equation |

Zeros | the zeros of a function are the x-intercepts of the graph |

Quadratic Function | the greatest exponent is 2 |

Quadratic Term | ax^2 |

Linear Term | bx |

Constant Term | c |

Parabola | the graph of a quadratic function |

Axis of Symmetry | a line through the graph of a parabola that divides the graph into two congruent halves |

Vertex | the axis of symmetry will intersect a parabola at only one point |

Maximum Value | greatest possible value the function can reach |

Minimum Value | lowest possible value the function can reach |
