## How can I be good at factorization?

Here are some basic tips that will help you to factor faster.

- Always start with real numbers: Students are more familiar with calculations with real number than variables, so working with real number will reduced the the amount of calculation and chance of making mistakes.
- Recognize common terms:
- cross multiplication.

## How do you know when you are done factoring?

We say that a polynomial is factored completely when we can’t factor it any more. Here are some suggestions that you should follow to make sure that you factor completely: Factor all common monomials first. Identify special products such as difference of squares or the square of a binomial.

## What do you call a polynomial that Cannot be factored?

A polynomial with integer coefficients that cannot be factored into polynomials of lower degree , also with integer coefficients, is called an irreducible or prime polynomial .

## How many terms should you have to consider factoring by grouping?

In some cases there is not a GCF for ALL the terms in a polynomial. If you have four terms with no GCF, then try factoring by grouping.

## What factoring method do we see if we can use when there are 4 terms?

When a polynomial has four or more terms, the easiest way to factor it is to use grouping. In this method, you look at only two terms at a time to see if any techniques become apparent. For example, you may see a Greatest Common Factor (GCF) in two terms, or you may recognize a trinomial as a perfect square.
