Whether you're a student learning algebra or a professional working with mathematical models, this tool will save you time and reduce errors.

How to Use This Calculator

Using our square expression calculator is simple and straightforward. Follow these steps to get accurate results:

Enter the expression you want to square in the input field. For example, you can enter "3x + 2" or "a - b".
Click the "Calculate" button to compute the squared expression.
Review the result displayed in the result panel. The calculator will show the expanded form of the squared expression.
If needed, you can reset the calculator to start a new calculation.

The calculator will handle both simple and complex expressions, including those with variables and constants. It follows standard algebraic rules to expand and simplify the squared expression.

Formula Explained

Squaring an expression (E) means multiplying it by itself:

E² = E × E

For example, if E is "3x + 2", then squaring it would be:

(3x + 2)² = (3x + 2)(3x + 2)

The calculator uses the distributive property of multiplication over addition to expand the expression:

(3x + 2)(3x + 2) = 3x × 3x + 3x × 2 + 2 × 3x + 2 × 2

= 9x² + 6x + 6x + 4

= 9x² + 12x + 4

This process ensures that the expression is squared correctly and simplified to its most reduced form.

Worked Examples

Let's look at a few examples to understand how the calculator works:

Example 1: Squaring a Binomial

Expression: (2x + 3)

Calculation:

(2x + 3)² = (2x + 3)(2x + 3)

= 2x × 2x + 2x × 3 + 3 × 2x + 3 × 3

= 4x² + 6x + 6x + 9

= 4x² + 12x + 9

Result: 4x² + 12x + 9

Example 2: Squaring a Monomial

Expression: 5y

Calculation:

(5y)² = 5y × 5y

= 25y²

Result: 25y²

Example 3: Squaring a Complex Expression

Expression: (a - b)

Calculation:

(a - b)² = (a - b)(a - b)

= a × a + a × (-b) + (-b) × a + (-b) × (-b)

= a² - ab - ab + b²

= a² - 2ab + b²

Result: a² - 2ab + b²
