## How can I be good at factorization?

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

1. 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.
2. Recognize common terms:
3. 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.
