TermDefinition
Axis of Symmetry ๐’™= ๐’ƒ/๐Ÿ๐’‚, 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’‚^๐Ÿโˆ’๐’ƒ^๐Ÿ=(๐’‚+๐’ƒ)(๐’‚ โˆ’๐’ƒ)
Discriminant ๐’ƒ^๐Ÿ โˆ’๐Ÿ’๐’‚๐’„, 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’Š= โˆš(โˆ’๐Ÿ)
Maximum highest point, vertex when a is negative
Minimum lowest point, vertex when a is positive
Perfect Square Trinomial ๐’‚^๐Ÿ+๐Ÿ๐’‚๐’ƒ+ ๐’ƒ^๐Ÿ=(๐’‚+๐’ƒ)^๐Ÿ
Purely Imaginary Number complex number where a = 0 and b โ‰  0 , 3i

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’™= ยฑโˆš๐’Œ
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’™)=๐’‚๐’™^๐Ÿ+๐’ƒ๐’™+๐’„
Vertex highest or lowest point of a parabola, where the graph turns: (h,k)
Vertex Form of a Quadratic Equation ๐’‡(๐’™)=๐’‚(๐’™ โˆ’๐’‰)^๐Ÿ+๐’Œ
X-Intercepts where graph crosses the x-axis, when y = 0
Y-Intercepts where graph crosses the y-axis, when x = 0

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
