- Introduction
- 6x2+5x-4
- Today we are going to learn about how to factor.
- What is Factoring?
- 6x2+5x-4
- Factoring is when you break down an equation into smaller numbers that equal that equation when multiplied.
- What is Factoring?
- 6x2+5x-4
- Once you finish breaking down the equation you will end up with something like this (x+a)(x+b)

- X Method
- 6x2+5x-4
-
- How to Do the X Method
- 6x2+5x-4
-
- The Answer
- 6x2+5x-4
-
- In order to solve this problem we are going to use something call the X method
- 6x2+5x-4 can be seen as ax^2+bx+c, so 6 is a, 5 is b and -4 is c. For the top part of X you would do a x c. For the bottom part you would put b. For the sides you would figure out which numbers multiply to a x c, but also add up to b. Once you get the numbers you divide it by a. You will get a fraction which you have to flip over to get your final answer.
- Answer: (3x-4)(2x-1)
- 8/6 = 4/3
- 5
- 6 x -4 = -24
- -3/6 = 1/2
- The answer is just a broken-down version of the original equation or polynomial.
- So when 6x2+5x-4 is factored or broken down, it equals (3x-4)(2x-1).
