Algebra covers a large portion of mathematics. We can say that algebra acts as a knot between different parts of mathematics. In this section, we will read algebraic formulas for class 8. We read elementary algebra to solve simple algebraic calculations. Algebraists (who are professionals of algebra) uses abstract algebra also known as modern algebra for research level preparations. But it has no deal with us. We should only focus on our level to do better.
Basics
It is a separate chapter in class 8 for you. It will be very easy to deal with when you go through these formulas at least once. Total back-through of the chapter will be in your hand. It will not be only for your present use but it will be used every time in each section of mathematics. At higher class, the algebraic formulas for class 8 which is here, you will use it in every step. So be careful and learn it accordingly. Solve as much example which uses these formulae as you can.
For our class, it is important to learn all the formula of algebra. It’s much less so it must be on our tongue which will help us solving problem fastly. The below-listed formulae will make you easy to see at a glance whenever you want to do so. Apart from subjective evaluation we simply at a page provided all the listing of algebraic formulas for class 8 according to your need.
Here is the list of all the formulas of algebra which will help you in getting revised everytime from this section.
| Algebraic Formulas For Class 8 |
| (a + b)2 = a2+ 2ab + b2 |
| (a − b)2 = a2 − 2ab + b2 |
| a2 – b2 = (a + b)(a – b) |
| (x+a)(x+b)=x2 + (a+b)x + ab |
| (x+a)(x–b)=x2 + (a–b)x – ab |
| (x–a)(x+b)=x2 + (b–a)x – ab |
| (x–a)(x–b)=x2 – (a+b)x + ab |
| (a+b)3 = a3 + b3 + 3ab(a+b) |
| (a–b)3 = a3 – b3– 3ab(a–b) |
