Solve for the Specified Variable $$\mathrm { S } = \lambda \left( \mathrm { b } ^ { 2 } + \mathrm { B } ^ { 2 } \right) \mathrm { w } ; \text { for } \mathrm { b }$$

Multiple Choice

Solve for the specified variable. Assume that all other variables are nonzero
- $$\mathrm { S } = \lambda \left( \mathrm { b } ^ { 2 } + \mathrm { B } ^ { 2 } \right) \mathrm { w } ; \text { for } \mathrm { b }$$

A) $b = \pm \sqrt { \frac { S - \lambda w B ^ { 2 } } { \lambda w } }$
B) $b = \pm \sqrt { \frac { S - B ^ { 2 } } { \lambda w } }$
C) $b = \pm \sqrt { \frac { S } { \lambda w } } - B ^ { 2 }$
D) $b = \pm \sqrt { \frac { S } { \lambda w } } - B$
