A Worked example to illustrate how the factoring calculator Works:
In the case of a nice and simple equation, the constants p,q,r can be determined through simple inspection.
Factoring by inspection is normally the first solution strategy studied by most students. The method forms the basis of studying other advanced solution methods such as quadratic formula and complete square methods.
Solving Quadratic Equations by Factoring
From the example above, the quadratic problem simply reduces to a linear problem which can be solved by simple factorization.
Example 1:
Given x^2+ 5x+ 6=0
\left(x+ 3\right)\left(x+ 2\right)=0 (factoring the polynomial)
\left(x+ 3\right)=0 OR \left(x+ 2\right)=0
Thus x=-3, Or x=-2
The example above shows that it is indeed easy to solve quadratics by factoring method. However, the method only works for the most basic equations. Ideally the method will only work on quadratics with rational roots. By default, the method will work on special functions, those with b= 0 or c= 0.
Thus, the litmus test for factoring by inspection is rational roots. With our online algebra calculator, you don’t have to worry about the nature of the roots to an equation. Simply type in your math problem and get a solution on demand.
First the calculator will automatically test if a particular math problem is solvable using the factoring method. The calc will proceed and print the results if the equation is solvable. Likewise, the calc will recommend the best solution method in case the polynomial is not factorable.

Solving equations by factoring with coefficients
While solving a quadratic equation though the factoring method, it is important to determine the right coefficients. Normally, the coefficients have to sum up to “b” (the coefficient of x) and they also have to have some common factors with either (a and b) or both. You don’t have to worry about finding the right factoring constant. The calculator does that automatically for you.
