Transcript of How to Factor
using the systematic method 1. Draw two sets of Parentheses side by side 3x 2 +7x+2 5x 2 +28x+15 Follow ME! Tutorial?? You bet!! 1. Draw two sets of Parentheses side by side, BUT make the back one bigger. Factoring the sum OR difference of cubes 8x -27 64+27x Follow along Method 6 Tutorial Number 7 !!Last Method!! Group terms so that you can factor twice Factor by Grouping not a big term but involves a lot of work to show x -ax+cx-ac 2 6x +4x-9xy-6y 2 Follow along, one more Final tutorial!! "Phew" I hope you learned something! 3 3 2. Put whichever letter that is being used in the front of each set of Parentheses 3. Think of two numbers you can multiply together to get the last number that also add up to the middle number and put one of these numbers in the back of the first set of Parentheses and the other in back of the second set of Parentheses 2. On the sides, write down factors of the first term and the last term 3. Find which sets will "Multiply and Add to the Middle" 4. Then put the sets that works in the Parentheses 2. In the first set, put the cubed root of the first term, the sign that appears first, and then the cubed root of the last term. 3. To get what goes in the second set, use the terms of the first set of Parentheses, by the following Put the square of the first term the opposite sign the product of the two terms (ignore signs) then the square of the last term
