Term | Definition |
---|---|
Axis of Symmetry | ๐= ๐/๐๐, line that divides parabola in a half through the vertex |
Completing the Square | method for rewriting a function, used for converting between standard and vertex forms; also process of adding a constant to both sides to make perfect square trinomial. |
Complex Conjugate | a pair of complex numbers, a + bi and a โ bi, whose real parts are the same but whose imaginary parts are oppositesex. 6 + 5i and 6 โ 5i |
Complex Number | numbers that use the imaginary unit i, andcan be written in the form, a + bi, where a and b are real numbers |
Difference of squares | ๐^๐โ๐^๐=(๐+๐)(๐ โ๐) |
Discriminant | ๐^๐ โ๐๐๐, used to determine number and type ofsolutions a quadratic equation has |
Distributive Property | a(b + c) = ac + bc |
Factoring By Grouping | technique involving grouping terms with common factors before factoring |
Imaginary Part of a Complex Number | the value of the realnumber b in the complexnumber a + bi |
Imaginary Number | complex number a + bi, in which b โ 0 |
Imaginary Unit | ๐= โ(โ๐) |
Maximum | highest point, vertex when a is negative |
Minimum | lowest point, vertex when a is positive |
Perfect Square Trinomial | ๐^๐+๐๐๐+ ๐^๐=(๐+๐)^๐ |
Purely Imaginary Number | complex number where a = 0 and b โ 0 , 3i |
Quadratic Equation | ๐(๐)=๐๐^๐+๐๐+๐, highest exponent is a 2 |

Real Part of a Complex Number | the value of the real number, a,in the complex number a + bi |
Roots | Solutions, Zeros |
Square Root Property | solving equation by taking the square root on both sides: ๐= ยฑโ๐ |
Standard Form of a Complex Number | a + bi, where a and b are real and i is imaginary |
Standard Form of a Quadratic Equation | ๐(๐)=๐๐^๐+๐๐+๐ |
Vertex | highest or lowest point of a parabola, where the graph turns: (h,k) |
