[1] Following the 2010 merger agreement between United and Continental Airlines, United Mileage Plus was chosen to be the frequent-flyer program for the combined airline. [2]
The number of positive real roots is at most the number of sign changes in the sequence of polynomial's coefficients (omitting zero coefficients), and the difference between the root count and the sign change count is always even. In particular, when the number of sign changes is zero or one, then there are exactly zero or one positive roots.

This is one method used when rounding to significant figures due to its simplicity. This method, also known as commercial rounding, [citation needed] treats positive and negative values symmetrically, and therefore is free of overall positive/negative bias if the original numbers are positive or negative with equal probability. It does, however ...
The quadratic formula can equivalently be written using various alternative expressions, for instance = (), which can be derived by first dividing a quadratic equation by , resulting in + + = , then substituting the new coefficients into the standard quadratic formula.
The number of steps between the operating lines and the equilibrium line represents the number of theoretical plates (or equilibrium stages) required for the distillation. For the binary distillation depicted in Figure 1, the required number of theoretical plates is 6. Constructing a McCabe–Thiele diagram is not always straightforward.
Method ringing is the continuously changing form of change ringing, and gets its name from the use of a particular method to generate the changes. After starting in repetitive rounds, at a given command, the ringers vary the bells' order, to produce a series of distinct sequences known as rows or changes.
