Basic formulas of algebra pdf

Basic formulas of algebra

All algebra formulas for all class are given. To solve algebra problem you need to all all the  algebra formulas.

For download basic formulas of algebra pdf click the download link below 

1. (a+b)^2 = a^2+2ab+b^2

                  = (a-b)^2+4ab
2. (a-b)^2 = a^2-2ab+b^2
                  = (a+b)^2-4ab

3. (a+b)^2 + (a-b)^2 = 2(a^2+b^2)

4. (a+b)^2 - (a-b)^2 = 4ab

5. a^2 + b^2 = (a+b)^2 - 2ab

                       = (a-b)^2 + 2ab

6. a^2 - b^2 = (a+b)(a-b)


For trigonometric formulas for class 10(x) are given. The link is given below
