just factor y to get
y = x(85-16x)
So, what is x when y=0 (that is, when it hits the ground)?
Adam kicks the football in his backyard. The path of the football when kicked can be represented by the quadratic function y = - 16{x^2} + 85x where x is the horizontal distance (in feet) and y is the height (in feet). How far does Adam kick the football? Express your answer as a decimal rounded to the nearest hundredth.
