Factoring Calculator
Factor a polynomial using the appropriate pattern, then check your result by expanding it.

See How Factoring Undoes Multiplication
Rewrite a polynomial by expressing it as a product of simpler factors. Start by looking for the greatest common factor, then consider the number of terms and the powers involved to identify the factoring pattern that applies.
A correct factorization should produce the original polynomial when the factors are multiplied together. Expanding the factors afterward is a simple way to confirm the result and catch any errors with signs.
Using the Factoring Calculator
Here is how to use factoring calculator:
Type in the Original Expression
Enter or paste the complete expression. You can also upload a clear photo or PDF and review the extracted text before solving.
Follow the Steps Behind the Result
Each step is clearly broken down and explained, allowing you to compare the process with your own approach.
Explore Any Step You Find Unclear
Stay within the same solution to try another method, verify a restriction, or understand why a particular rule applies.
Recognizing a Difference of Squares
The difference between two perfect squares can be factored into a pair of conjugate binomials.
a² − b² = (a − b)(a + b)
A Simple Method for Factoring Expressions
A reliable approach is to work through the following steps:
Find the Greatest Common Factor
Find the greatest factor shared by every term before trying any other factoring pattern.
Factor Quadratic Trinomials
Choose terms that multiply to ac and add to b, then group them.
Recognize Common Special Products
You can recognize some special products by adding them
Worked Example: Factor 6x² + 11x -10
ac = 6 (-10) = -60 Find the product of leading coefficient and constant.
15+(-4)= 11 Find the factors of -60 that sum to 11.
6x² + 15x − 4x − 10 Break the middle terms into two terms.
3x(2x + 5) − 2(2x + 5) Factors each set of terms.
(3x-2) (2x+5) Take out the common binomial factor.
The complete Factorization is (3x-2) (2x+5)
Common Factoring Errors to Avoid
Here are some common factoring mistakes to watch for.
Overlooking the GCF
Factoring is incomplete when all the terms still contain common factors.
Mistaking a Sum of Squares for a Factorable Pattern
Unlike a² − b², a² + b² does not factor over the real numbers in the same way.
Forgetting to Check by Multiplication
Expanding the factors confirms the middle term and sign choices.
