To solve this problem, use vertex form: \(y = a(x-h)^2 +k\), where the vertex occurs at \((h,k)\)

Substituting the vertex, we have: \(y = a(x-2)^2 - 1\).

Now, plugging in the point \((3,1)\) and solving for a tells us that \(a = 2\).

This means that the quadratic in vertex form is \(2(x-2)^2 - 1 = \color{brown}\boxed{2x^2 - 8x + 7}\)
