Question

To
verify algebraic identity
(a+b)3=a3+3ab(a+b)+b3
​

Answer 1

Answer:

To verify the identity (a+b)3 = a3 + b3 + 3a2b + 3ab2 geometrically by using sets of unit cubes. A set of 128 plastic cubes or wooden cubes with dimensions (1unit x 1unit x 1unit). To verify the identity (a+b)3 = a3 + b3 + 3a2b + 3ab2, we shall take value of a = 3units and value of b = 1unit.
