Simplify the following rational expression. $$\frac{x^3 - 9x}{4x^2} - \frac{2x^2 - 2}{4x^2 - 4x + 3} = \frac{x^2 + 3x}{5x + 5}$$ Select the correct choice below and fill in the answer box to complete your choice. (Simplify your answer.)

A. $$\frac{x^3 - 9x}{4x^2} - \frac{2x^2 - 2}{4x^2 - 4x + 3} = \frac{x^2 + 3x}{5x + 5}$$ $$x \neq 3, -1, 0, 1, 3$$

B. $$\frac{x^3 - 9x}{4x^2} - \frac{2x^2 - 2}{4x^2 - 4x + 3} = \frac{x^2 + 3x}{5x + 5}$$ $$x \neq 5, 3$$

Perform the following subtraction. $$\frac{4x}{x^2 + 7x - 8} - \frac{3x}{x^2 + x - 2}$$ Select the correct choice below and fill in the answer box to complete your choice. (Simplify your answer.)

A. $$\frac{4x}{x^2 + 7x - 8} - \frac{3x}{x^2 + x - 2}$$ $$x \neq -2, 1, 8$$

B. $$\frac{4x}{x^2 + 7x - 8} - \frac{3x}{x^2 + x - 2}$$ $$x \neq 8, -2, 1$$

Simplify the following rational expression. $$\frac{x^4 - 16}{x^2 - 4} - \frac{x^2 - 4}{x^2 + 4} = \frac{x^2 + 4}{x + 2}$$ Select the correct choice below and fill in the answer box to complete your choice. (Simplify your answer.)

A. $$\frac{x^4 - 16}{x^2 - 4} - \frac{x^2 - 4}{x^2 + 4} = \frac{x^2 + 4}{x + 2}$$ $$x \neq 2, -2, 0, 4$$

B. $$\frac{x^4 - 16}{x^2 - 4} - \frac{x^2 - 4}{x^2 + 4} = \frac{x^2 + 4}{x + 2}$$ $$x \neq 4, 2$$
