Quadratic Function
a function that can be described by an equation of the form f(x) = ax2 + bx + c, where a ≠ 0.
Standard Form of a quadratic Function and Vertex Formula of a Quadratic Function
both formulas determine if the parabola faces up or down and the Vertex also determines how wide the parabola will be
Zero product property
If the product of two or more factors is zero then at least one of the factors should be zero
Factoring
used to simplify expressions, simplify fractions, and solve equations.
DIFFERENCE OF SQUARE
AN EXPRESSION WITH TWO TERMS WHICH ARE BOTH PERFECT SQUARES
PERFECT SQUARE TRINOMIAL
1ST,LAST TERM ARE PERFECT SQUARES, MIDDLE TERM IS 2X THE PRODUCT OF THE 1ST TERM
QUADRATIC FORMULA
THE SOLUTION OF THE QUADRATIC EQUATION
Discriminant
The name of the expression underneath the radical sign.
It's important because it tells us the numbers and types of solutions we have to solve.
IMAGINARY NUMBERS
A NUMBER THAT EQUALS ZERO WHEN IT IS SQUARED
COMPLEX NUMBERS
A COMBINATION OF A REAL AND IMAGINARY NUMBER
