What is cube of binomial definition?

The cube of a binomial refers to the expression ((a + b)^3) and can be expanded using the binomial theorem. It is defined as ( (a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3 ). This expansion includes the sum of the cubes of the individual terms and three times the products of the squares of each term with the other term. The formula can also be applied to ((a - b)^3), yielding a similar structure with alternating signs.
