Two of the steps in the derivation of the quadratic formula are shown below.

Step 6: = b^2-4ac/4a^2 = (x+b/2a) ^2

Step 7: = + ✔️b^2-4ac/2a = x + b/2a

Which operation is performed in the derivation of the quadratic formula moving from Step 6 to Step 7?

subtracting b/2a from both sides of the equation squaring both sides of the equation taking the square root of both sides of the equation taking the square root of the discriminant
