Solve for the Indicated Variable $$y = k x ( 4 - x ) , \quad \text { for } x$$

question 37

Multiple Choice

Solve for the indicated variable. Assume the variable you are solving for must be greater than 0.
- $$y = k x ( 4 - x ) , \quad \text { for } x$$

• A) \[x = \frac { k + \sqrt { k ^ { 2 } - k y } } { 2 k }\]
• B) \[x = \frac { 2 k + \sqrt { 4 k ^ { 2 } - 2 k y } } { 2 }\]
• C) \[x = \frac { 2 k + \sqrt { 4 k ^ { 2 } - k y } } { k }\]
• D) \[x = \frac { 2 k + \sqrt { k ^ { 2 } + k y } } { k }\]
