Let p(x)=x^3 - a x , where a is constant and a>0 .

Find the local maxima and minima of

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

maxima and minima:
