Consider the equation: $$\frac{5}{x^2-9}=\frac{2}{x-3}$$ Which of the following describes all values of $x$ that must be excluded from the domain?

True or False: The rational equation $\frac{x-1}{x^2-1}=\frac{1}{x+1}$ is satisfied by all real numbers except $x=1$ and $x=-1$.

Find the solution set for the following equation: $$\frac{2}{x-1}=\frac{x}{x-1}-1$$

True or False: If an algebraic step in solving a rational equation leads to $x=2$, but the original equation had a term $\frac{5}{x^2-4}$, then $x=2$ must be rejected as an extraneous solution.

Two printers work together to finish a job. Printer A takes $x$ minutes to print the job alone, while Printer B takes $x+5$ minutes. If they can complete the job together in 6 minutes, which rational equation represents this scenario?
