To factor a polynomial, you must first find the greatest common factor (GCF) of all its terms. Once you have done this, you can use that GCF to rewrite each term as a product. 

The greatest common factor can also be used to split the polynomial into two parts if you want. For example, x2 + 8×2 – 9x + 2 is split into 3×3 and 8×2 9. 

Another common method for factoring is the difference of squares. This is often found when you are factoring perfect square trinomials and sums or differences of cubes. 

When using this method, you will need to know how to write a binomial for the coefficients of each term. This will help you figure out which factors belong to each group. 

Typically, a binomial will contain the square root of each term, the sign of the middle term, and the square root of the last term. Often, these numbers will be the same in all groups. 

The other option is to split the polynomial into terms that aren’t related in any way to each other. If you aren’t sure how to do this, ask your teacher for help. 

If the equation has a single term, you can also factor it out by looking at its exponents. For example, x2 + 3x = 8x – 6 is factored as (x+4)(x-4). 

There are several other techniques that you can use to factor expressions, such as finding the prime factorization of a number or reversing the multiplication process. Once you have mastered these techniques, factoring expressions will be a breeze! 

Generally, the best technique for factoring an expression is to break it up into smaller expressions. This will allow you to see the factors more easily and can make it easier to find the common factors that all of the expressions share. 

You can also look at the exponents of the terms and factor out the largest ones. This is a great strategy for figuring out how to factor a trinomial with a large number of terms. 

For this reason, it is helpful to use a key number. This will tell you what the coefficients of the highest term are and the other terms in the expression will be able to be figured out easily. 

It is important to note that if an expression has a large number of terms, the number of possible factors increases. If it has only a few terms, you may not need to factor in the expression at all. 

Similarly, it is important to remember that when you are factoring an equation, you need to equate the roots to zero. This will ensure that each of the factors you’re using is a real number. If you’re not careful, you could end up with a factor that is actually imaginary!
