Algebra 2, Chapter 4

parabola the graph of a quadratic function
axis of symmetry a line through the graph of a parabola that divides the graph into two congruent halves
vertex the point at which the axis of symmetry intersects intersects the parabola
quadratic function a function that contains a quadratic term, a linear term, and a constant term
maximum value the greatest possible value a function can reach
minimum value the lowest possible value a function can reach
quadratic equations quadratic functions that are set equal to zero
roots solutions of a quadratic equation
FOIL method method that uses the Distributive Property to help multiply binomials
pure imaginary numbers square roots of negative real numbers
complex number any number that can be written in the form a+bi, where a and b are real imaginary numbers and i is the imaginary unit
completing the square a method that can be used to solve all quadratic equations by using the Square Root Property and manipulating the equation until one side is a perfect square
discriminant the expression b^2-4ac, which is used to determine the number and type of roots of a quadratic equation
standard form ax^2+bx+c=0, where a does not equal zero and a, b, and c are integers
zeros these are used to find the roots of a quadratic equation and are the x-intercepts of the graph of a quadratic equation
factored form 0=a(x-p)(x-q), where p and q represent the x-intercepts of a graph of the equation
Zero Product Property for any real numbers a and b, if ab=0, then either a=0, b=0, or both a and b equal zero
imaginary unit i i^2=-1; the number i is the principal square root of -1
Square Root Property a method that is similar to a difference of squares and is used to solve quadratic equations
factoring finding the terms that are multiplied together to get an expression

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.
