2. How is a bar graph different from a double bar graph in CBSE Class 8 Maths?

In data handling, bar graphs and double bar graphs are very common. A bar graph is a graphical representation of a single set of data along bars of the same width and heights proportional to the data value. In a bar graph, you will see single bars one after the other. In a double bar graph, there is a graphical representation of two sets of data simultaneously. So, you see double bars next to one another which are used for comparison.

4. What is regrouping in CBSE Class 8 Maths?

Regrouping, in simple words, is arranging the terms to make factorisation easy. For example, let’s take 2xy + 3 + 2y + 3x. We see here that factorisation is not easy. So, we arrange them into: 2xy + 2y + 3x + 3. This allows us to form the following groups: (2xy+3x) and (2y+3). Its factorisation will give the factors (2y+3) and (x+1). If you multiply (2y+3) (x+1), you will get the same answer, i.e, 2xy + 3 + 2y + 3x.
