Week #9 Factoring Out GCF in Trinomials

The first thing you want to do when removing the GCF in a trinomial is find all the factors of each number. Each number that has similar factors you can begin to remove, you want to place the factor you chose and move it outside of the brackets as well as dividing that number out of the trinomial, the number you get from dividing the factor goes inside the brackets. This makes factoring much easier. I chose simple examples which in my first example my numbers were 5, 15, and 10 and the factor I removed and divided by was 5x because in the trinomial each number had (X) in it. In my second example I had numbers 6, 9, and 18 and I removed 3 and divided each number by 3.
