quadratic equation
	Any equation where at least one term has degree 2 and no term has degree higher than 2.  The standard equation Ax2 + By2 + Cxy + Dx + Ey + F = 0  represents all quadratic relations in one or two variables.  (pp. 23, 171, 177, 188)
quadratic formula
	This formula gives you the solutions , for a quadratic equation in one variable that can be written in the standard form ax2 + bx + c = 0.  (p. 23)
quadratic function
	A quadratic equation that can be written y = ax2 + bx + c is also a quadratic function where x is the independent variable and y is the dependent variable.  Its graph is a parabola with a vertical orientation.  The graphing form of a quadratic function is f(x) = a(x − h)2 + k.  (pp. 177, 188)
quadratic relation

	The conic sections are quadratic relations.  See “general quadratic equation,” “quadratic equations,” “parabola,” “ellipse,” and “hyperbola.”  (p. 593)
quotient
	The result of a division problem is a quotient with a remainder (which could be 0).  When a polynomial p(x) is divided by a polynomial d(x) the a polynomial q(x) will be the quotient with a remainder r(x).  The product of q(x) and d(x) plus the remainder r(x) will equal the original polynomial. p(x) = d(x)q(x) + r(x) .  (p. 472)
