Once again, I've gotten lost. I need to simplify:
. . .(2x<sup>2</sup> - 2x)/(x<sup>3</sup> - 4x<sup>2</sup> - x + 4) - (16)/(2x<sup>3</sup> - 6x<sup>2</sup> - 8x)
I realize I need to find the LCD (the Least Common Denominator) and, before doing this, I need to factor out my denominators. I came up with:
. . .[2x(x - 1)] / [(x<sup>2</sup> - 1)(x - 4)] . . .-. . . 4<sup>2</sup> / [2x(x - 4)(x + 1)]
But after this, I got lost.
