Answer:

completing the square

Step-by-step explanation:

Two steps are given for the derivative of quadratic formula.

In completing the square method, we take the coefficient of x and then divide it by 2 and then square it.

Here coefficient of x is b/a

\frac{b}{a} divide by 2 becomes \frac{b}{2a}

Then we square it

(\frac{b}{2a}) becomes(\frac{b}{2a})^2

So, the competing the square took place between the first and second step
