In this second part we continue our journey. We shall soon see how the humble quadratic makes its appearance in many different and important applications. In mathematics, the inequality of arithmetic and geometric means, or more briefly the AMвЂ“GM inequality, states that the arithmetic mean of a list of non-negative real numbers is greater than or equal to the geometric mean of the same list; and further, that the two means are equal if and only if every number in the list is the same.

In mathematics, an inequality is a relation that connects two numbers or other mathematical objects. (see also: equality). The notation a < b means that a is less than b. The notation a > b means that a is greater than b. In either case, a is not equal to b. These relations are known as strict inequalities, meaning that a is strictly less than b. A quadratic inequality of the form y > a x 2 + b x + c (or substitute <, в‰Ґ or в‰¤ for >) represents a region of the plane bounded by a parabola. To graph a quadratic inequality, start by graphing the parabola.

To solve a quadratic inequality in the form of a[x.sup.2] + bx + c < 0 or in the equivalent form c[x.sup.2] + dx + e < Ax + B most of the college algebra text books use either the sign chart for the left-hand side of the first inequality or graphs both functions which appear in each side of the second inequality (e.g., Swokowski & Jeffery, 2000).
