In your role as a technical analyst verifying algebraic setups, you are preparing to perform the division $(x^4 - x^2 + 5x - 6) \div (x + 2)$ using long division. Which placeholder term must be added to the dividend to maintain the required column alignment for all powers of $x$?

In your role as a technical QA tester, you are verifying the output of an algorithm designed to perform polynomial long division.

True or False: When the algorithm divides $(x^4 - x^2 + 5x - 6)$ by $(x + 2)$, the final numerical remainder before being written as a fraction is $-4$.

In your role as a quality assurance specialist for an educational software company, you are verifying the 'Step-by-Step Solution' generated for the division $(x^4 - x^2 + 5x - 6) \div (x + 2)$. Arrange the following terms in the order they should appear in the finalized quotient, starting from the term with the highest degree and ending with the remainder term.

In your role as a Quality Assurance Specialist for an educational software company, you are verifying the technical accuracy of an algebra module. You are reviewing the long division setup for the problem: $(x^4 - x^2 + 5x - 6) \div (x + 2)$. To ensure the documentation is correct, match each mathematical component with its corresponding functional role or value as it would appear in the division process.
