Question

Add the following -:

10a,10b
​

Answer 1

Answer:

10a + 10 b = 10 (a+b)

square on both sides

100a² + 100b² = 100 (a+b)²

100(a²+b²) = 100 (a+b)²

cancel 100 on both sides

a²+b² = (a+b )²

(a+b)² = a²+b²+2ab *formula *

a²+b² = a²+b²+2ab

Answer 2

Answer:

10a and 10b cannot be added as the variables i.e. a and b is not common.

Ex-

10a+10a = 20 a.

OR

10b+10b =20b.

Hope it helps :)
