The (x,y) at the point of the vertex is usually called the (h,k)"h" is calculated by the formula h = -b / (2*a)h = -18 / (2 * -3)h = 3To get the "k" value, enter the value of "h" in the equation.–3x2 + 18x + 2"k" = -3*3*3 + 18*3 + 2-27 + 54 + 2"k" = 29the vertex at (3, 29)Source:http://www.1728.org/quadr3.htm
