D = $\sqrt({F+P})$ / (F-P) find P
You asked:
Solve the equation \[D = \frac{\sqrt{F + P}}{F - P}\] for the unknown \(P\).
MathBot Answer:
$$\begin{aligned}P &= \frac{2 D^{2} F + 1}{2 D^{2}} - \frac{\sqrt{8 D^{2} F + 1}}{2 D^{2}}\\P &= \frac{2 D^{2} F + 1}{2 D^{2}} + \frac{\sqrt{8 D^{2} F + 1}}{2 D^{2}}\end{aligned}$$ and \(P \neq F\)
