9-5 Factoring (Standard Form to Factored Form)


FACTORED FORM: Any quadratic equation in the form y = (x - a)(x - b)

FACTORING: To break up terms into smaller like terms (for this unit, to go from standard to factored form)

LINE OF SYMMETRY: The vertical line through the vertex, splits parabola into two mirror-image pieces

QUADRATIC EQUATION: A polynomial with a highest term of x2

PARABOLA: A graph of a quadratic equation

POLYNOMIAL: Any finite set of terms with positive exponents being added, subtracted, or multiplied

ROOTS/ZEROS: The point or points where a parabola intersects the x-axis.

STANDARD FORM: Any quadratic equation in the form: y = ax2 + bx + c

VERTEX: The point on the graph where the parabola changes direction from positive to negative or negative to positive
