comment When will one maximum turn into three maximums?
@ClaudeLeibovici, by distinct, I mean when there exists three maximum solutions to the equation y'(x) = 0, as opposed to x = 0 being the only such solution.

@Winther, can you help me with this similar quesiton: math.stackexchange.com/questions/1219657/…

@ClaudeLeibovici, I was more interested in whether there was a way to manipulate to find x, rather than the solutions themselves. Claude are you able to help on this queston: math.stackexchange.com/questions/1219657/…

@Winther, yes I was able to figure that one out.

@Winther, yes there should be 3 solutions for x. One is x = 0 and the other two depend on the value of k.
