2014新gre考试实施以来,不仅对写作部分茫然不知所措,就连我们所擅长的数学也甚是担忧,相信这其中的原因还是由于考生在新gre数学复习时没有把基础打牢。如果新版gre数学基本考点都没有复习到,如何能拿到分数呢?所以说,想要新版gre数学考好,复习的时候一定要把基本概念和重要考点都弄扎实。
今天针对新版gre数学复习,小编给大家整理的是关于Roots of Polynomial的相关内容,这些概念在考试中一定会考到的。希望考生能再接再厉,取得一个好成绩,突破新版gre数学难的困境。
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.
由于美国数学基础教育的难度增加导致数学考试越来越难,但新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。
