    You have to use the equation editor with a few extra steps. I assume you know how to factor the three trinomials?

    Um...before you do that, factor the three individual trinomials. Try factoring: \(x^{2} + 2x - 3\).

    Not quite. What are factors of -3 that add to 2?

    No. -2 x -1 = 2. Not -3. You did it the opposite way. They should add to 2 and multiply to -3.

    YAY! \(x^{2} + 2x - 3 = (x - 1)(x + 3)\) Now, let's factor \(x^{2} - 2x + 1\)

    You're getting really good! \(\large\frac{(x + 1)(x + 1)}{(x + 3)(x - 1)} \times \frac{(x - 1)(x - 1)}{(x + 3)(x + 1)} = \frac{\cancel{(x + 1)}(x + 1)}{(x + 3)\cancel{(x - 1)}} \times \frac{\cancel{(x - 1)}(x - 1)}{(x + 3)\cancel{(x + 1)}} = \frac{(x + 1)(x - 1)}{(x + 3)(x + 3)}\)Yup :) You got it!
