    I have to find the vertex, axis of symmetry, and x intercepts of x^2-x+(5/4). I put it in standard form as -(x+-.5)^2+1.5. Thus, the vertex would be .5, 1.5. But the book's answer is 1/2, 1. How did they get this?

    Are binary compounds ionic or covalent? If they are covalent, I thought they don't form bonds that way, since they share electrons.
