complete the square to rewrite y=x^2-6x+14 in vertex form then state whether the vertex is a maximum or minimum and give its coordinates

To rewrite a quadratic in standard form to vertex form, you should complete the square. Start by writing down the original equation, in standard form. y=x^2 + 4x - 5. Because the coefficient of the x^2 term is 1, we can use a simplified process. Look at the x term. Take half of its coefficient and square that.
