question 81

Multiple Choice

Solve the formula for the indicated letter. Assume that all variables represent nonnegative numbers.
- $a S ^ { 2 } + b S = c$ , for $S$

• A) \(S = \frac { - b + b ^ { 2 } - 4 a c } { 2 a }\)
• B) \(S = \frac { - b + b ^ { 2 } + 4 a c } { 2 a }\)
• C) \(S = \frac { - b + \sqrt { b ^ { 2 } + 4 a c } } { 2 a }\)
• D) \(S = \frac { - b + \sqrt { b ^ { 2 } - 4 a c } } { 2 a }\)
