    or it is x=(sum of roots)/2

    ok but for me i cant get the roots until i get the axis of symmetry. it turns into 4/(-2/4) for some reason

    sum of roots = -coefficient of x/coefficient of x^2 you don't need to find the roots

    so if i do do that it would be: sum of roots= -4/(-1/4) right?
