SOLUTION: Combine the terms and simplify as much as possible: p^2/2mr^2-gmM/r

Question 246966: Combine the terms and simplify as much as possible:
p^2/2mr^2-gmM/r
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
[p^2/2mr^2] - [gmM/r]
-----------------------------
lcd = 2mr^2
-------------------
Rewrite each fraction with the lcd as its denominator:
-------
[p^2/lcd] - [gmM(2mr)/lcd]
---
Combine the numerators over the gcd:
[p^2 - 2gm^2Mr].cd
---
[p^2 - 2gm^2Mr]/(2mr^2)
==============================
