hi im not sure if this is in the right 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
differentiating this function would be a good starting point. use the differentiation shortcuts to find f'(x), then set it equal to zero or undefined. Because this is a polynomial, all you need to do is set f'(x) equal to zero because it is never undefined.
I hope this helps you get started.
