Question

Let p(x)=x^2(a−x), where a is constant and a greater than 0.

Find the local maxima and minima of p.
(Enter your maxima and minima as comma-separated xvalue,classification pairs. For example, if you found that x=−2 was a local minimum and x=3 was a local maximum, you should enter (-2,min), (3,max). If there were no maximum, you must drop the parentheses and enter -2,min.)

My answer was -2a/3 for the local min.... and that's it, but that's wrong....

Answer 1

Oh ok I got it... the local max is 2a/3 and the local min 0....

Answer 2

yup
