Question

Here are two steps from the derivation of the quadratic formula

Answer 1

Answer:

C

Step-by-step explanation:

Completing the square means

adding ( half the coefficient of the x- term )² to both sides, that is

( $\frac{b}{2a}$ )² is added to both sides

Answer 2

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
