Check the detailed explanation for the question What Is a cube plus b cube plus c cube ? here for your reference about the formula of a cube plus b cube plus c cube . b is the Second Variable This formula gives the sum of cube of two numbers without actually calculating the cubes. a3 + b3 Formula Proof The sum of cube formula or a3 + b3 formula is proved by solving the RHS part of the formula and then simplifying the same to make it equal to the LHS. The a3 + b3 formula is, a3 + b3 = (a + b ) (a2 - ab + b2) a cube plus b cube is written as a^3 + b ^3 and its formula says a^3 + b ^3 = (a + b )(a^2 - ab + b ^2). Learn how this formula works and how it can be applied with a few solved examples. A cube B cube formula may be considered as a cube plus b cube formula or a cube minus b cube formula. These two formulas are used to expand the binomial expressions and evaluate the numerical expressions without actually calculating the cubes.
