In mathematics, one of the fundamental topics that students encounter is solving equations. Equations often come in different forms, including linear, quadratic, and even cubic equations. One particular type of equation that many students find challenging yet fascinating is the A + B + C whole square equation. This type of equation involves finding the solutions for an expression that is a perfect square of the form (A + B + C)^2. In this article, we will explore the concept of the A + B + C whole square equation, discuss the methods for solving it, and provide examples to illustrate the process.
Understanding the A + B + C Whole Square Equation
To break down the A + B + C whole square equation, let’s first consider it in its expanded form:
(A + B + C)^2 = A^2 + B^2 + C^2 + 2AB + 2AC + 2BC
In this equation, A, B, and C are constants or variables. The goal when solving the A + B + C whole square equation is to find the values of A, B, and C that satisfy the given equation. This process involves identifying patterns, simplifying expressions, and applying algebraic techniques to arrive at the solutions.

Sometimes, solving the A + B + C whole square equation involves using substitution and simplification techniques. By substituting known values or expressions into the equation and simplifying the resulting equation, you can work towards identifying the values of A, B, and C. This method may involve multiple steps but can be effective in solving complex A + B + C whole square equations.
Examples of Solving the A + B + C Whole Square Equation
Let’s illustrate the process of solving the A + B + C whole square equation with a few examples:
Example 1:
Given: (A + B + 5)^2 = A^2 + B^2 + 25 + 2AB + 10A + 10B
Solution:
-
Expand both sides of the equation:
(A + B + 5)(A + B + 5) = A^2 + B^2 + 25 + 2AB + 10A + 10B
A^2 + 2AB + 5A + 2AB + B^2 + 5B + 5A + 5B + 25 = A^2 + B^2 + 25 + 2AB + 10A + 10B -
Simplify the equation:
A^2 + 4AB + 10A + 5B + B^2 + 10B + 25 = A^2 + B^2 + 25 + 2AB + 10A + 10B -
Compare coefficients:
4AB = 2AB
10A + 5B = 10A
10B = 10B -
Solve for A, B, and C:
A = 0, B = 0, C = 5
Example 2:
Given: (2A + 3B + 4)^2 = 4A^2 + 9B^2 + 16 + 12AB + 24A + 36B
Solution:
-
Expand both sides of the equation:
(2A + 3B + 4)(2A + 3B + 4) = 4A^2 + 9B^2 + 16 + 12AB + 24A + 36B
4A^2 + 6AB + 8A + 6AB + 9B^2 + 12B + 8A + 12B + 16 = 4A^2 + 9B^2 + 16 + 12AB + 24A + 36B -
Simplify the equation:
4A^2 + 12AB + 16A + 6AB + 9B^2 + 24B + 16A + 36B + 16 = 4A^2 + 9B^2 + 16 + 12AB + 24A + 36B -
Compare coefficients:
12AB = 12AB
16A + 6AB = 24A
16A + 9B^2 + 24B = 36B -
Solve for A, B, and C:
A = 4, B = 0, C = 4
