One way to check for factorability is the quadratic formula. It gives the solutions of quadratic equations in terms of roots and coefficients. **If a polynomial is not factorable, then it cannot be factored by the quadratic formula**. The most common reason for this is that it has roots in an infinite number of places.

RULE # 1: The First Rule of Factoring: **Always see if you can factor something out of ALL the terms**. This often occurs along with another type of factoring.

**When should you solve by factoring?**

Factoring only works **if the solutions to a quadratic equation are rational numbers**.

**When should we solve by factoring?**

Solve by factoring is used **to solve equations that have an x ^{2} (or higher) term in them**. Factoring is when something is broken into pieces that _multiply_ to give the original, for example 35 is factored as 5 * 7.

**What to do if you can't factor?**

When asked to solve a quadratic equation that you just can't seem to factor (or that just doesn't factor), you have to employ other ways of solving the equation, such as by **using the quadratic formula**. The quadratic formula is the formula used to solve for the variable in a quadratic equation in standard form.

**What numbers Cannot be factored?**

**Prime numbers** have two factors, themselves and 1, but those are the trivial factors that every number has. Because they cannot be factored in any other way, we say that they cannot be factored.

**Can any number be factored?**

Factorization was first considered by ancient Greek mathematicians in the case of integers. They proved the fundamental theorem of arithmetic, which asserts that **every positive integer may be factored into a product of prime numbers**, which cannot be further factored into integers greater than 1.

**What polynomials Cannot be factored?**

**How do you tell if something is a factor of a function?**

**Any time you divide by a number (that number being a potential root of the polynomial) and get a zero remainder in the synthetic division**, this means that the number is indeed a root, and thus "x minus the number" is a factor.
