    Which points on curve are tangents horizontal?

    y=2x^3-9x^2-60x+3 I have to find points where tangents are horizontal. If tangents are horizontal that means the gradient is 0? I'm not sure how to go about this. y'=9x^2-18x-60 is the derivative of the line. Not really sure. Do I sub in x=0? y'=0-0-60 y'=-60 lol, no idea.
