A bаsebаll is hit intо the аir. Its height, H in metres, is given by the quadratic relatiоn:H = -5t² + 25t, where t is the time in secоnds after the ball is hit. Algebraically determine the maximum height of the baseball by converting to factored form, using the zeros to find the axis of symmetry, then vertex.  Show all of your steps.
