Question

to verify a3+b3 =(a+b) (a2-ab+b2)​

Answer 1

Step-by-step explanation:

To verify the identity a3 – b3 = (a – b)(a2 + ab + b2) geometrically by using sets of unit cubes. To verify a3 – b3 = (a – b)(a2 + ab + b2). Let a = 3 and b =1. Take 27 cubes and place them to form a stack consisting of a 9 columns, each column consisting 3 cubes [fig.
