Factoring trinomials with the box method

It will look like this when we're done

​Our goal is to find out how to turn

3x²-x-2 into (3x-2)(x+1) using the same boxes that we did before.

First set up your grid and put the first term and the last term in the first full box and the last full box.​

3x²+x-2

​To figure that out, we need to find the pair of numbers that multiplies to be the first number times the last, but adds to the middle number.

The tough part is we need to figure out what goes in the other two full boxes.​

​

What pair of numbers multiplies to be -6 but adds to 1?

​

Order doesn't matter!

​Put these numbers with a variable in the remaining boxes

​Find the greatest common factor of each row and column.
