When it comes to algebra and mathematics, there are various formulas and theorems that play a crucial role in solving equations and simplifying complex expressions. One such formula that is often used in algebraic manipulations is the A plus B whole cube formula. This formula enables us to expand the cube of a binomial, i.e., the sum of two terms raised to the power of three. Understanding and applying this formula can significantly simplify calculations and help in solving equations efficiently.
Understanding the A plus B Whole Cube Formula
To grasp the concept of the A plus B whole cube formula, let's consider two variables, A and B. The formula states that (A + B)³ is equal to A³ + 3A²B + 3AB² + B³. This expansion provides us with the individual terms resulting from cubing the binomial (A + B).
Let's break down the formula step by step to understand how it is derived and how it can be applied in mathematical calculations:
Derivation of the A plus B Whole Cube Formula
 Start with the Cube of the Binomial:
(A + B)³ = (A + B)(A + B)(A + B)
 Apply the Distributive Property:
(A + B)(A + B)(A + B) = (A + B)(A² + 2AB + B²)
(A + B)(A² + 2AB + B²) = A(A²) + A(2AB) + A(B²) + B(A²) + B(2AB) + B(B²)
 Multiply and Simplify:
A³ + 2A²B + AB² + A²B + 2AB² + B³
 Combine Like Terms:
A³ + 3A²B + 3AB² + B³
Application of the A plus B Whole Cube Formula
Now that we have the expanded form of (A + B)³, let's look at an example of how this formula can be applied in practice:
Example:
Expand and simplify (2x + 3)³
Solution:
(2x + 3)³ = (2x)³ + 3(2x)²(3) + 3(2x)(3)² + 3³
= 8x³ + 36x² + 54x + 27
