finding stationary points using differentiation

Postby mannilea on Mon Oct 19, 2009 7:35 pm

hiya not sure where this should go so sorry if it is in the wrong place

curve is y=(2-x)(x+1)^2

show that one stationary point is at x=-1

find the coordinates if both stationary points

any help much appreciated

Where are you stuck? You applied the Product Rule to differentiate the given function, you set the result equal to zero, and... then what?

Please be complete. Thank you! :wink:
