1 thought on “verify the identity<br /><br />a3<br />
+ b3<br />
= (a + b) (a2<br />
– ab + b2<br />
)<br /><br />please answer fast in LHS=”
To verify the identity a3 + b3 = (a + b) (a2 – ab + b2) geometrically by using sets of unit cubes. A set of 56 cubes each has dimensions (1 x 1 x 1) cubic unit. Cubes may be of wood, plastic, cardboard or thermocol. To verify the identity a3 + b3, we shall take a = 3 units and b = 1 unit.
