Algebraic Formulas Used in the Calculator

This calculator is based on standard algebraic identities. Let’s understand each formula in detail.

1. Square of a Sum

Formula:
(a + b)² = a² + 2ab + b²

This identity helps expand the square of a binomial sum.

2. Square of a Difference

Formula:
(a – b)² = a² – 2ab + b²

This is used when subtracting two variables inside a square.

3. Difference of Squares

Formula:
a² – b² = (a – b)(a + b)

This identity helps factorize expressions quickly.

4. Square of Three Terms

Formula:
(a + b + c)² = a² + b² + c² + 2ab + 2ac + 2bc

This is used for expanding expressions involving three variables.

Example of Algebraic Proof Calculation

Let’s understand how the calculator works with an example.

Given:

a = 3
b = 4
Expression: (a + b)²

Step 1: Apply Formula

(a + b)² = a² + 2ab + b²

Step 2: Substitute Values

= (3 + 4)²
= 7²

Step 3: Final Calculation

= 49

Calculator Output:

Expanded Result: 49
Formula: a² + 2ab + b²
Step Explanation: Shows identity used

This makes algebraic learning faster and easier.
