Documenting the Procedure for Combining Rational Expressions

As part of a process improvement initiative at your company, you are documenting the mathematical models used in your department's logistics software. One of these models requires adding the rational expressions: 3x3+2x2\frac{3}{x-3} + \frac{2}{x-2}. Based on the standard procedure for adding rational expressions with distinct denominators, outline the three-step process used to find their sum. In your response, explicitly state the rule for determining the Least Common Denominator (LCD) and explain how the numerators are adjusted before being combined.
