A laboratory technician is using a rational equation to model the concentration of a chemical solution over time: $\frac{15}{x^2+x-6} - \frac{3}{x-2} = \frac{2}{x+3}$. To ensure the model is mathematically valid and avoid a system error caused by division by zero, the technician must identify the 'restricted values' for the variable $x$. Which of the following sets represents these restricted values?

A data analyst is solving the equation $\frac{15}{x^2+x-6} - \frac{3}{x-2} = \frac{2}{x+3}$ to verify the logic in a resource-balancing tool. Match each key component of the solution process with its correct value or description.

A systems analyst is optimizing a resource-allocation script that uses the rational equation $\frac{15}{x^2+x-6} - \frac{3}{x-2} = \frac{2}{x+3}$ to balance server loads. After performing the algebraic steps, the analyst calculates a potential value of $x = 2$. However, because this value results in a division-by-zero error in the original formula, it is classified as an ____ solution.

A quality control specialist is documenting the procedure to solve the rational equation $\frac{15}{x^2+x-6} - \frac{3}{x-2} = \frac{2}{x+3}$ for a density calculation tool. Arrange the following steps in the correct chronological order as described in the technical manual.

A software testing engineer is validating a program that calculates load distribution using the equation $\frac{15}{x^2+x-6} - \frac{3}{x-2} = \frac{2}{x+3}$. The calculated value $x = 2$ is a valid mathematical solution that can be safely used in the program.
