Data Validation and the Square Root Property

You are a quality assurance analyst reviewing a technical report for a logistics firm.

Your supervisor asks you to explain why this calculation results in 'No Real Solution.' State the fundamental mathematical rule regarding the square of real numbers that you must recall to justify why no real-world value for vv can be found using this equation.
