Using the completing-the-square method, rewrite f(x) = x2 − 8x + 3 in vertex form.

The vertex-form of a quadratic equation is , where (h, k) is the vertex of the parabola.

To complete the square of a quadratic expression in standard form, we write the coefficient of x as 2*b, then add and subtract  .





so b=4, now add and subtract .
