Definition
What is it?
The expression (a+b+c) whole square means multiplying the sum of three numbers (a, b, and c) by itself. It's written as (a+b+c)^2. This concept helps us quickly expand and simplify expressions involving three terms added together and then squared.
Simple Example
Quick Example
Imagine you have three friends, Rohan, Priya, and Sameer. Rohan has 2 cricket bats, Priya has 3, and Sameer has 1. If you want to know the 'square' of their total bats, you would calculate (2+3+1)^2. First, add them up: 2+3+1 = 6. Then, square the total: 6^2 = 36.
Worked Example
Step-by-Step
Let's find the value of (2+3+4) whole square.
1. First, identify the values of a, b, and c. Here, a=2, b=3, c=4.
---
2. Add the numbers inside the bracket: 2 + 3 + 4 = 9.
---
3. Now, square the sum: 9^2.
---
4. This means multiplying 9 by itself: 9 * 9.
---
5. Calculate the product: 9 * 9 = 81.
---
So, (2+3+4) whole square is 81.
Why It Matters
Understanding (a+b+c) whole square helps solve problems faster in subjects like Physics for calculating areas or volumes, and in Computer Science for optimizing code. Engineers use this concept when designing structures or circuits, making sure everything fits perfectly and works efficiently.
Common Mistakes
MISTAKE: Squaring each term separately and adding them: (a^2 + b^2 + c^2) | CORRECTION: Remember to add the terms first, then square the sum: (a+b+c)^2. The square applies to the entire sum, not individual terms.
MISTAKE: Forgetting the brackets and just squaring the last term: a+b+c^2 | CORRECTION: The 'whole square' means the entire expression (a+b+c) is multiplied by itself. Always keep the brackets in mind.
MISTAKE: Confusing (a+b+c)^2 with (a+b+c) * 2 | CORRECTION: Squaring means multiplying a number or expression by itself, not by 2. (a+b+c)^2 means (a+b+c) * (a+b+c).

Option C correctly shows that 'whole square' means multiplying the entire sum (5+2+3) by itself. Options A, B, and D show incorrect ways of calculating a whole square.
Real World Connection
In the Real World
Imagine an architect designing a new building in Mumbai. They might need to calculate the total length of three different sections of a wall, say 'A', 'B', and 'C', and then use (A+B+C) whole square in formulas to determine the total material needed or the stress on certain points. This ensures the building is strong and safe.
