A manufacturing technician is simplifying a stress-testing formula used to evaluate material durability. They need to simplify the expression $\frac{x^2 - 4x - 32}{64 - x^2}$ to make it easier to input into their analysis software. Arrange the following steps in the correct order to simplify this expression using the rule for opposite factors.

A financial analyst is reviewing a training manual on simplifying cost-to-revenue models. According to the standard procedure for simplifying rational expressions, what should the analyst do when they encounter binomial factors in the numerator and denominator that are exact opposites (such as $x - 5$ and ${}5 - x$)?

A quality control technician is simplifying a calibration formula for a pressure sensor. The formula contains the rational expression $\frac{x - 100}{{}100 - x}$. According to the rule for simplifying rational expressions with opposite factors, when the technician cancels these two terms, they should be replaced with the numerical constant ____.

A structural engineer is simplifying a stress-analysis formula and derives the expression $\frac{x - 45}{{}45 - x}$. True or False: Because the numerator and denominator are opposite factors, the engineer should simplify this expression to 1.

A training supervisor at an aircraft manufacturing firm is instructing a group of quality control apprentices on how to simplify formulas used in fuel-efficiency calibrations. One of the calibration models compares forward-flow and reverse-flow sensor rates, yielding formulas that contain opposite binomial factors. The supervisor uses the rational expression $\frac{x^2 - 4x - 32}{64 - x^2}$ as a case example. To demonstrate your understanding of the standard algebraic steps and outcomes for simplifying rational expressions with opposite factors, match each part of the simplification process with its mathematically correct description or result.
