Let me insert in this chapter on roots certain necessary results that are said to be key, and they are clearly demonstrated in Euclid's second book; it suffices to proceed to the definitions of them according to arithmetic [1]. The first of them is with the number separated into parts;...
The intercepts of an unknown cubic function... If a cubic function has three x-intercepts, or roots, r1, r2, and r3, we can express its equation in the factored form y=a(x−r1)(x−r2)(x−r3) The other constant a can then be determined from the value of the y-intercept. ...

Any reducible tree can be written as a sum of irreducible ones, where the sum U⊕V of two trees U and V is defined as the tree obtained by identifying the roots of U and V into a new root with label root(U)+root(V)−1. See Fig. 2, taken from [1], for an example. ...
This article has a preliminary research on the conditions of the duplicate roots existing in the cubic functions defined on the real number collection. 本文用初等的方法研究了定义在实数集上的三次函数存在重根的条件,并且讨论了各种特殊的三次函数的实根问题,还研究了具有实重根的三次函数在特定的实数区间...
Corrected feed-forward signal 160 is received by the whitening filter 162 for pre-whitening (digital inverse filtering) to compensate for the later analog anti-alias filtering done by the low-pass filter 164. Whitening filter 162 is preferably a FIR filter with numerator roots in the z-transfer...
