用整数或表达式除以多项式其实是一种简化方式。 其实没有什么新的东西要学：你只需要简化数值（比如20/15简化为4/3），并且知道如何用指数来除法（当你用指数除法，请减去幂，所以x^7 / x^3 = x^4）。 将多项式除以一个数字（或整数），需要遵循3个简单的步骤 : (1)把题目改写成分数。 (2)把每数值写成个别分数(而每个数字写在分母上)。 (3)将每项分数简化。 例子：（8a+10b-14）/2。 (1)改写为分数(8a+10b-14)/2。 (2)分成8a/2+10b/2-14/2。 (3)8a除以2得4a。10b除以2是5b。而14除以2就是7。 答案：4a+5b-7。 超简单！我们按照同样的3个步骤进行单项式的除法（记住，单项式是只有一个变量的表达式）。 请访问我们的网站：www.fuseschool.org，在这里，我们所有的视频都按主题进行了精心的分类编排，并了解我们还能提供什么。评论、点赞并与其他同学分享。你可以提问和回答问题，老师会回答你。 这些视频可以采用翻转课堂的模式，也可以作为复习辅助工具。 Twitter: https://twitter.com/fuseSchool 本开放教育资源是免费的，并采用知识共享许可协议进行许可。归属-非商业 CC BY-NC ( 见许可证文件：http://creativecommons.org/licenses/by-nc/4.0/ )。 你可以下载该视频用于非营利性、教育性目的。如果你想修改视频，请联系我们：info@fuseschool.org。 点击这里查看更多视频：https://alugha.com/mysimpleshow

Interest is the amount charged by a lender to a borrower. It means that if you borrow some money from a bank, you have to pay back more than the money you borrowed. Equally, if you have a savings account and deposit some money, the bank will pay you interest as a sort of thank you for saving with th
In this video we are going to look at a few different ways in which plant hormones can be used. Plant growth hormones (auxins) can be used as selective weedkillers. The selective weedkillers contain growth hormones, that cause the weeds to grow really quickly. This means the weed is absorbing nutr
Algebraic fractions are simply fractions with algebraic expressions either on the top, bottom or both. We treat them in the same way as we would numerical fractions. In this video we look at how to simplify algebraic fractions, and how to add and subtract them. VISIT us at www.fuseschool.org, wh
