I'm not sure how to solve this..a baseball is popped straight up into the air and has a hang-time of 6.25s. Determine the height to which the ball rises before it reaches its peak.

I'm trying to solve by completing the square but i always get stuck at the end.. 3x^2-6x+2=0 3(x^2-2x)+2=0 3(x^2-2x+1-1)+2=0 3(x-1)^2 -1 =0 3(x-1)^2=1 now what do i do?... the answer is supposed to be x=3+-(square root)of3-> the whole thing over 3

write the equatopm pf a line that passes through(3,-1) and is parrallel to the line y=-2x+1
