a) (-2,16)

b) (-1, 18)

c) (1,4)

d) (2,0)

I found the derivative of y=(x-2)^2(x+3)

which is 3x^2-2x-8

if I solved for 0, it wouldn't give me the answer that are listed above. What did I do wrong?

**MathMate**, Sunday, February 19, 2012 at 5:19pmdy/dx=3x^2-2x-8 is good.

I get x=-3/4 or x=2 for dy/dx=0.

So can you find the answer from above?
