Factor Any Expression

Step 1: Enter your expression below

Step 2: Click the Blue Arrow to factorize!

How does it work?

Enter your problem in the box above and click the blue arrow to submit your question (you may see a range of appropriate solvers (such as "Factor") appear if there are multiple options). If you're not sure what to enter, look over the sample problems below to see the types of expressions this tool can factorise. In addition to the completely free factored result, considering upgrading with our partners at Mathway to unlock the full step-by-step solution.

Example Problems

Try typing these expressions into the calculator, click the blue arrow, and select "Factor" to see a demonstration. Or, use these as a template to create and solve your own problems.

Problem: \(4x^2-9\)
Solution: \((2x+3)(2x-3)\)

Problem: \(x^4-81\)
Solution: \((x^2+9)(x+3)(x-3)\)

Problem: \(x^2-7x-18\)
Solution: \((x-9)(x+2)\)

Final Thoughts

You may want to read up on the quadratic formula to help your algebra knowledge rather than relying on this solver. Afterall, the point is to learn the concept, not just get the answer... right?

Also, while this calculator page is tailored for algebraic expressions, you might be looking to solve for the prime factorization of a number. For example, finding all the prime numbers that divide into 56 (7 and 2). We also have a page on the greatest common factor and a link for least common multiple available.
