| Completing the square | a way of simplifying or solving a quadratic equation by adding an expression to both sides to make one part of the equation a perfect square |
| constraints | A limitation usually imposed upon either the domain of a function or the range of a function. In linear programming, the constraint tells you to only consider a certain range of inputs and the constraints are represented as linear inequalities |
| complex solutions | The x-values that make the function equal to zero are complex numbers (have an imaginary part) |
| discriminant | The expression in a quadratic equation . It can be used to determine the characteristics of the solution. |
| extracting roots | refers to applying the square root property as a means of solving a quadratic equation. |
| quadratic equation | A polynomial equation in which the highest power of the variable is two. The general form of such equations in the variable x is |
| Quadratic Formula | The formula for determining the roots of a quadratic equation from its coefficients |
| real solutions | Solutions of the variable that make the equation true but are either rational numbers or irrational numbers |
| zeros of a function | the x-value or x-values that make the function equal to zero. A zero may be a real number or a complex number. A zero will never be an imaginary number. |
