Quadrant I contains all coordinates with positive x and positive y values Quadrant II contains all negative x and positive y values; Quadrant III contains all negative x and negative y values; and Quadrant IV contains all positive x and negative y values.
Quadratfrie - square free.
Quadratic Equation - an equation of the form f(x)=0 where f(x) is a second degree polynomial. That is, ax2+bx+c=0. A term used in pre-Algebra and Algebra.
Quadratic Function - a function of the form f(x) = ax2 + bx + c where a is not equal to zero (in which case the function turns into a linear function).
Quadrature - the quadrature of a geometric figure is the determination of its area.
Quadric Curve - the graph of a second degree equation in two variables.
Quadric Surface - the graph of a second degree equation in three variables.
