| Coefficient | The number (constant term) in front of a variable in an algebraic term. |
| Degree | (1) In geomtry, a unit for measuring angles. (2) The unit for measuring temperature. |
| Vertex | Top, the highest part or point. A point where two or more adjacent lines meet for form an angle or a corner. In plane or solid figures, the point opposite the base. |
| Axis Of Symmetry | The line that divides something in half so that one half is the mirror image of the other half. A shape may have more than one. |
| Polynomial | A monomial or a sum of monomials. |
| Binomial | The sum of two monomials. |
| Quadratic Equation | One is which the value of the related quadratic function is 0. |
| Quadratic Formula | The roots of a quadratic equation in the form ax² + bx + c = 0, where a does not equal 0, are given by the formula x = -b plus or minus the square root of b² - 4ac all divided by 2a. |
| Vertex Form | A quadratic function in the form y = a(x – h)² + k, where (h, k) is the vertex of the parabola and x = h is its axis of symmetry. |
| Polynomial Form | f(x) = ax² + bx + c |
| Factored Form | A monomial is expressed as the product of prime numbers and variables where no variable has an exponent greater than 1. |
| X-Intercept | The coordinate at which a graph intersects the X-axis. |
| Solution Of A Quadratic Equation | X-intercepts of the graph. |
| Double Root | Occurs when the quadratic is a perfect square trinomial. |
| Solve By Factoring | 1. Move all terms to one side of the equation, usually the left, using addition or subtraction. (2) Factor the equation completely. (3) Set each factor equal to zero, and solve. (4) List each solution from Step 3 as a solution to the original equation. |
| Difference Of Two Squares | Two perfect squares separated by a subtraction sign, a² - b² = (a + b)(a - b). |
| Perfect Square Trinomial | When factored has the form (a + b)² = (a + b)(a + b) or (a - b)² = (a - b)(a - b). |
