Hello, finalfantasy!

The factors can be found like this, right? . . . . . Right!

So therefore: .[1].and .[2]. . . . Yes!

For [1]: . , you move 1 over,

. . so it becomes: .

. . You then divide by 3, so it equals: .

. . It then becomes: . . . . . Good!

but that's as far as I know how to do it.

Now do the same for [2]: .

Move the -3 over: .

And this equation hasnosolution.
