Complete the square to re-write the quadratic function in vertex form:

Answer 1

In vertex form the parabola can be expressed as:

y = (x - 2.5)² + 0.75

Explanation:

To complete the square, all you need to do is take the term 5x, divide the coefficient in two, and square it. That is what you need for the third term:

`y = x^2 - 5x + 7\\y = x^2 - 5x + 6.25 + 0.75\\y = (x - 2.5)^2 + 0.75`
