0 is both a number and the numerical digit used to represent that number in numerals. The number 0 fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems.

Yogita Ingle 7 years ago

(a + b)³ = a³ + 3a²b + 3ab² + b³
(a + b)³ = a³ + b³ + 3ab(a + b)
(a – b)³= a³ – 3a²b + 3ab² – b³
a³ – b³ = (a – b)(a²+ ab + b²)
a³ + b³ = (a + b)(a² – ab + b²)
(a + b)³ = a³ + 3a²b + 3ab² + b³
(a – b)³ = a³ – 3a²b + 3ab² – b³
