What is my Algebra 1 teacher going to ask my module 3 DBA specifically?

Greatest Common Factor: integer or variable multiplied by other integers or variables that create a resulting product. factor x factor = product

difference of squares binomial: an expression where two perfect square terms are being subtracteda² - b² = (a+b)(a-b)quadratic: from "quad" meaning square, because the variable gets squared (like x2).

discriminant: tells you about the roots of a quadratic
general form: y = a(x - h)^2 + kstandard form: ax^2 + bx + c = 0root: a solution of an equation

zero: a value that gives you 0 for a function
x-intercept: where the graph crosses the x-axis

y-intercept: where the graph crosses the y-axis
extraneous: a solution that does not work
parabola: the graph of a quadratic
vertex: the turning point of the parabola
axis: line of reflection

translation: movement up/down and left/right of any parabola from standard position (f(x) = x2)

The basics of what you should know is listed above.
