Adding $\frac{2n}{n^2-3n-10} + \frac{6}{n^2+5n+6}$

True or False: The Least Common Denominator (LCD) for $\frac{8}{x^2 - 2x - 3} + \frac{3x}{x^2 + 4x + 3}$ contains exactly three binomial factors because the denominators share a common factor.

Arrange the steps to add the rational expressions $\frac{8}{x^2 - 2x - 3}$ and $\frac{3x}{x^2 + 4x + 3}$ in the correct order.

When adding the rational expressions $\frac{8}{x^2 - 2x - 3}$ and $\frac{3x}{x^2 + 4x + 3}$, the Least Common Denominator (LCD) is $(x + 1)(x - 3)(x + 3)$. Which expression represents the sum of the numerators after each has been multiplied by its missing factor (before expanding)?

Match each part of adding the expressions $\frac{8}{x^2 - 2x - 3} + \frac{3x}{x^2 + 4x + 3}$ to its correct result.

Why is the rational expression $\frac{3x^2 - x + 24}{(x + 1)(x - 3)(x + 3)}$ considered to be in its simplest form?

Factor the denominators of $\frac{8}{x^2 - 2x - 3}$ and $\frac{3x}{x^2 + 4x + 3}$. Their shared binomial factor is _____.

What is the least common denominator (LCD) for the rational expressions $\frac{8}{x^2 - 2x - 3}$ and $\frac{3x}{x^2 + 4x + 3}$?
