For example, finding all the prime numbers that divide into 56 (7 and 2). right?Īlso, while this calculator page is tailored for algebraic expressions, you might be looking to solve for the prime factorization of a number. Afterall, the point is to learn the concept, not just get the answer. You may want to read up on the quadratic formula to help your algebra knowledge rather than relying on this solver. I forgot how to factor! I don't know where to start.challenge question - Factor the polynomial completely.Perhaps you can learn from the questions someone else has already asked. Here are some questions other visitors have asked on our free math help message board. Solution: \((x-9)(x+2)\) Common Factoring Questions Or, use these as a template to create and solve your own problems. Try typing these expressions into the calculator, click the blue arrow, and select "Factor" to see a demonstration. In addition to the completely free factored result, considering upgrading with our partners at Mathway to unlock the full step-by-step solution. If you're not sure what to enter, look over the sample problems below to see the types of expressions this tool can factorise. If you choose to write your mathematical statements, here is a list of acceptable math symbols and operators.Factor Any Expression Step 1: Enter your expression below Step 2: Click the Blue Arrow to factorize! How does it work?Įnter 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). To avoid such uncertainties, we encourage you to rely on our equation calculator. Lastly, the method involves some form of trial and error while finding the right constants. On the other hand, there no sure way of determining whether or not an equation is solvable using the factoring method. Thus, not all quadratics can be solved using the above method. Limitation of factoring as a way to solve quadraticsĪlthough the method is highly efficient, it is only applicable to equations with rational roots. The following examples will solidify your understanding of factoring as a solution method to quadratic equations: Learning mathematics is best done with examples. You would want to find two constants h, k such that h+k= 5, and h*k=4.ġ and 4 are such candidates: Thus we can rewrite the expression as The following example shows the basics of solving a quadratic through factoring. In the latter form, the problem reduces to finding or solving linear equations, which are easy to solve. If ax^2+ bx + c = 0, where a ≠ 0 is a factorable quadratic equation, then it can be represented in the form ax^2+ bx + c = (x+h)(x+k)=0, where h, k are constants. To solve a quadratic through this method, we first factor the equation into a product of two first degree polynomials as given in the following example: The method is dependent on the fact that if a product of two objects equals zero, then either of the objects equals zero. Solving quadratic equation through factorization is one of the classical methods of solving quadratics. The factoring quadratic solver lets you factor and solve equations of the form ax^2+ bx + c = 0, where a \ne 0.
