Build quadratic and exponential functions from context using explicit formulas, recursive processes, or calculation steps.

Write a quadratic area function from variable side lengths

Problem

For rectangle side lengths \(2x+3\) and \(x-1\), write the area as their product and expand it. Then solve both positivity conditions to give the physical domain and distinguish linear from square units.
