Answer 2

Answer:

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

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

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

4.(53)^2 = (50 +3)^2

5.(97)^2 = (100-3)^2

6. 3x-9y = 3( x -3y)

7.x^2 - y^2 =(x+y) (x-y)

8.(a+b)^3 = a^3 +b^3 +3ab (a+b)

9. ( a-b) ^3 = a^3 - b^3 - 3ab(a +b)

10. Cube of x +4 = (x+4)^3

Hope this will help :)
