Multiple Choice

Solve the equation for the specified variable.
- $\mathrm { f } = \frac { \mathrm { f } _ { 1 } \mathrm { f } _ { 2 } } { \mathrm { f } _ { 1 } + \mathrm { f } _ { 2 } } \quad$ for $\mathrm { f } _ { 2 }$

• A) \(f _ { 2 } = \frac { f - f _ { 1 } } { f _ { 1 } - f }\)
• B) \(f _ { 2 } = \frac { f f _ { 1 } } { f _ { 1 } - f }\)
• C) \(f _ { 2 } = \frac { f f _ { 1 } } { f _ { 1 } + f }\)
• D) \(f _ { 2 } = - 1\)
