Manipulating the centered difference approximation

Click For Summary
SUMMARY

The forum discussion centers on manipulating the centered difference approximation in the context of atmospheric and meteorological equations. The primary objective is to demonstrate the equivalence of two equations, specifically transforming the quadratic equation a*x² + b*x + c = 0 to solve for x. Participants emphasize the importance of correctly applying the radical sign over the division by R in the calculations. This highlights the need for precision in mathematical manipulations within meteorological applications.

The equation is attached in the image file. I tried several times to work it out but I can't figure this out for the life of me. They just want me to show that the first equation equals the second one. Any atmospheric/meteorology majors out there? Any help in general would be appreciated.

Treat it as a*x**2 + b*x + c = 0 and solve for x. The radical sign should extend over the division by R.
