    Problem 1.
    Consider the equation y=a(x-r_1)(x+r_2)
    Write the equation of the axis of symmetry.

    That is just a simple parabola:
    [tex]y = ax^2 - ax(r_1 - r_2) - ar_1r_2[/tex]
    Where is the 'vertex' of this parabola? What is its X coordinate?

    How do you get the axis of symmetry..vertex..etc...

    How would you get the axis of symmetry: x=-b/2a from b=-ax(r_1-r_2) and a= 1 or just a???
