Okay, I have no clue what I am doing wrong. I've been following part a of this http://www.webassign.net/latex2pdf/2a2176c1f300dcc09b8a130c84af8595.pdf solution to help me with part a of this question I'm stuck on: If a rock is thrown upward on the planet Mars with a velocity of 18 m/s, its height (in meters) after t seconds is given by H = 18t − 1.86t^2. Find the velocity of the rock after two seconds. No matter what I do, it's still the wrong answer and it's becoming really frustrating considering that notes that my professor gave my class doesn't help with this at all.
