NCERT Polynomials Ex.2.2 all solutions | Chapter 2 | CBSE | Class 9
Hello everyone!
This is a step-by-step explanation to the solutions of all of the problems of second exercise 2.2 of the second chapter polynomials of Class 9 of NCERT Maths Book. In this exercise, we discuss about values of polynomials at different values of variables such as x, a, t, etc. After that we talk about zeroes of polynomials; how to identify and find zeroes of different polynomials given in the question.
I hope this video was helpful to you.

Class 9 Ex:1.4 Rationalize the Denominators |NCERT Maths|CBSE
Просмотров 472 месяца назад
In this video, we try to learn how to rationalize the denominators of the given fractions. To rationalize the denominators, we need to know about three basic things which are described in the video. If you know these three basic things then it is pretty much easy to rationalize any types of fractions. If you have any confusions, let us know in the comments below. If you liked our video, don't f...

Class 9 Ex:1.3.RECURRING DECIMALS INTO FRACTIONS (NON-TERMINATING ONES!) |NCERT Maths|CBSE
Просмотров 949 месяцев назад
Hello everyone! This one is about converting non-terminating recurring decimal expansions into fractions. We just need to know a few tricks to solve these types of questions. The first one is assuming the given number as some random variable such as "x" then we multiply the variable with powers of 10 depending on the number of digits that are recurring in the given question. And finally subtrac...
Class 9 Ex:1.3.Convert Fractions into Decimals |NCERT Maths|CBSE |Chapter 1
Просмотров 539 месяцев назад
Hello everyone! In this video, we will be converting the given fractions into decimal forms and then also determine what type of decimal expansion each of them have. There are three types of decimal expansions. They are terminating, recurring non-terminating and non-recurring non terminating. In the first part of the video, we talk about these three types of decimal expansions. And since ration...
Class 9 Ex:1.1.Find rational numbers between two numbers |NCERT Maths|CBSE
Просмотров 939 месяцев назад
Hello everyone! We are solving some questions about number systems in maths. Here, we talk about what is a rational number, is zero a rational number; if so why it is a rational number, and can it be written in the form of p/q? Similarly, we try to find rational numbers between numbers and fractions in two different ways. The first method is more of an intuition type and the second one is more ...
HOW TO FIND MODE (EASY) | INDIVIDUAL, DISCRETE AND CONTINUOUS SERIES | STATISTICS
Просмотров 809 месяцев назад
#seemath #mathspreparation #exampreparation Hello everyone! Mode is one of the easiest topics in statistics. Here, we find the mode of three types of data; individual, discrete, and continuous data. Mode is the item that repeats the most in a data set. In the individual and discrete data, it is a one-step solution whereas in the continuous data, you do have to use a formula but the formula is e...

#seemath #mathspreparation #exampreparation Hello everyone! How to find the missing frequency when the median is given in the question? So, the way to solve these types question is we try to find the median from the given data even though the median is given in the question. When we are using the formula of the median, we can put the value of the median which is given in our question. After tha...

#seemath #mathspreparation #exampreparation Hello everyone! In this video, we will look at five different types of questions related to median so that you won't be able to say, "Oh! We have never seen a question like this in class and the question is new in your exam". We start with two examples of individual series, a normal one and one where the position of the median comes in points. Then we...

#seemath #mathspreparation #exampreparation Hi everyone! In our previous video, we discussed how to find the mean of individual, discrete, and continuous data. In this one, we talk about how we can find the missing frequency when the mean is given in the question. I have tried to explain how we can find the missing frequency with an example question. You can apply the same logic to any question...
