quadratic Algebra. involving the square and no higher power of the unknown quantity; of the second degree.
Discriminant b² - 4ac
Parabola the graph of a quadratic function is u-shaped
vertex the highest or lowest point on the parabola
axis of symmetry the vertical line through the vertex
factoring finding an equivalent expression to an expression that is a product of expressions
greatest common factor the product of scaler factoring
prime solution solution is not factorable
primary and secondary root primary = positive root from solution of radical secondary = negative root from solution of radical
imaginary unit i
square root property take square root of both sides of equation after squared variable is isolated
4 methods to solve quadratic equations 1) table of values 2) factoring 3) completing the square 4) quadratic formula
Quadratic Function A function of the form y = ax 2 + bx + c , where a≠ 0 , and a , b , and c are real numbers.
Standard Form a, b and c are known values. a can't be 0.
complex solutions When the Discriminant (the value b2 - 4ac) is negative we get Complex solutions ... what does that mean?
Plus/Minus ±
zeros They are also called "roots", or sometimes???
Quadratic Formula x = [ -b ± √(b2-4ac) ] / 2a
Completing the Square is a technique used to solve quadratic equations, graph quadratic functions, and evaluate integrals. This technique can be used when factoring a quadratic equation does not work or to find irrational and complex roots.
square root property is one method that is used to find the solutions to a quadratic (second degree) equation. This method involves taking the square roots of both sides of the equation. .
