| Completing the Square | the process of rewriting a quadratic equation so that one side is a perfect square trinomial. |
| Complex Number | a number a + bi where a and b are real numbers and i is the imaginary unit |
| Conjugate | the result of writing sum of two terms as a difference or vice-versa. |
| Discriminant | the expression b^2 - 4ac for the quadratic equation ax^2 + bx + c. |
| Exponential Function | a function of the form y = a·b^x where a > 0 and either 0 < b < 1 or b > 1. |
| Extraneous Solution | a trial soluton that does not satisfy the original equation. |
| Polynomial | the sum or difference of terms which have variables raised to positive integer powers and which have coefficients that may be real or complex. |
| Quadratic Equation | an equation written in the form ax^2 + bx + c=0. |
| Rational Exponent | represented by both an integer exponent and an nth root, where the root is found in the denominator, and the integer exponent is found in the numerator. |
| Symmetry | something that has a mirror image over a line in space. |
