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.
