a) use the quadratic formula
b) set x=0 in the original equation
c) use x=-b/2a to get the x-coordinate of the vertex. then use this value and sub it into the original equation to find the y coordinate
d) equation for the axis of symmetry is x= (the x coordinate the vertex)

Please next time type in the entire equation
