Complex trinomial 

A complex factoring doesn't start with a coefficient of x^2. 

The common factor has to be in each term, not just one or two, all three of them have to have the common factor. 2 is a common factor in this expression. So you take 2 out of this expression. Now if you were going to expand this you would get the same expression.

Example 1:

Find a common factor. If there’s no common factor, you go straight to factoring.

Factor

Factor the simple trinomial, which is inside the bracket. Remember to make the 2 brackets first (      ) (      ). The first numbers in both the brackets multiply to the first term. The next numbers have to multiply to the third term. You factor this just like the simple trinomial. 

Check if your right

Expand and simplify

Example 2:

Find a common factor. If there’s no common factor, you go straight to factoring.

There is no common factor between any of them. 

Factor

When you factor this remember that in each bracket there has to be No COMMON FACTOR between them. When it gets factored and the bracket still has a common factor it won’t work. You need to find the factors of the first and last term so it’s a trial and error.

Won’t work

When you get the wrong sign you just change the sign with the other factor
