This tool helps you rewrite complex polynomials into their simpler component factors, making algebra problems easier to solve and understand. It is ideal for students learning polynomial factorization, verifying homework, and preparing for math exams.

If you are working on complex equations, using an Algebra Calculator can help you check your step-by-step solutions quickly.

What Is Factoring?

Factoring is the process of breaking down a mathematical expression or polynomial into a product of simpler terms (factors). When these factors are multiplied back together, they yield the original expression.

Example

$x^2 + 5x + 6 = (x + 2)(x + 3)$

Factoring is essentially the reverse process of expanding brackets:

• Expanded Form: $x^2 + 5x + 6$
• Factored Form: $(x + 2)(x + 3)$

How to Use the Factoring Calculator

1. Enter the Expression: Input the polynomial or algebraic expression into the designated box.
2. Check Your Inputs: Ensure all variables, coefficients, and operators ($+$, $-$, $\times$) are typed correctly.
3. Calculate: Click the Enter or Calculate button to process the expression.
4. Review Results: Study the factored output along with the detailed breakdown of the steps.

Step-by-Step Example: Factoring a Quadratic

Problem: Factor the quadratic expression $x^2 + 7x + 12$.

• Step 1: Identify key values.

  • Coefficient of $x$ (middle term) = $7$
  • Constant term (last term) = $12$

• Step 2: Find two key numbers. Find two numbers that multiply to $12$ and add up to $7$:

  • $3 \times 4 = 12$
  • $3 + 4 = 7$

• Step 3: Write the factored form. Using these two numbers, rewrite the expression as a product of two binomials: $x^2 + 7x + 12 = (x + 3)(x + 4)$

Common Factoring Techniques

| Method | Description | Formula / Example | | :--- | :--- | :--- | | Greatest Common Factor (GCF) | Factor out the largest term common to all terms in the expression. | $6x + 12 = 6(x + 2)$ | | Difference of Squares | Applies when subtracting one squared term from another. | $a^2 - b^2 = (a - b)(a + b)$• $x^2 - 16 = (x - 4)(x + 4)$ | | Factoring by Grouping | Group terms with common factors into pairs to solve higher-degree polynomials. | $ax + ay + bx + by = a(x + y) + b(x + y) = (a + b)(x + y)$ | | Quadratic Trinomials | Break down $ax^2 + bx + c$ into two binomials using factor pairs. | $x^2 + 7x + 12 = (x + 3)(x + 4)$ |
