一、改变观念初中数学知识相对比较浅显,更易于掌握,通过反复练习,可较快提高成绩。特别在初三,通过大量的练习,对知识的掌握达到了一定的熟练程度,可使你的成绩有明显的提高。即使是这样,某些同学对有些问题理解还不够深刻,例如:求解x2-5x-6=0的根,一些同学就解不出来,不会因式分解,不会配方,不知道求根公式。刚上高一,第一章就是集合,常常会遇到含参一元二次方

First, change the concept of junior high school mathematics knowledge is relatively simple, easier to master, through repeated practice, can improve performance faster. Especially in the third year, through a lot of exercises, mastery of knowledge has reached a certain degree of proficiency, and your performance can be significantly improved. Even so, some classmates have not deep enough understanding of some issues. For example: Solving the root of x2-5x-6=0, some students will not be able to solve it, will not be factorized, will not formulate, do not know the root formula . Just a freshman, the first chapter is a collection, often encountered with a one-element quadratic
