新版gre数学复习重要考点:Roots of Polynomial
The number c is a root of a polynomial p, if p=0.
An n-th order polynomial has n complex roots.
Example:
2 is a root of polynomial p=x-2,since p=2-2=0.
1 is a root of polynomial p=x2-3x+2,since p=12-31+2=0.
Remember:
A polynomial may not have any real root:p=x2+1 does not have any real root, since p=1 for all real x.
很多新版gre数学复习考点都是高中时候学到的知识点,考生不要过于紧张,把基本概念弄明白,再记住一些新版gre数学必备的词汇,那么相信新版gre数学应该没有问题。
