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 |
