Two of the steps in the derivation of the quadratic formula are shown below.
Step 6: StartFraction b squared minus 4 a c Over 4 a squared EndFraction = (x + StartFraction b Over 2 a EndFraction) squared
Step 7: StartFraction plus or minus StartRoot b squared minus 4 a c EndRoot Over 1 a EndFraction = x + StartFraction b Over 2 a EndFraction
Which operation is performed in the derivation of the quadratic formula moving from Step 6 to Step 7?
subtracting StartFraction b Over 2 a EndFraction 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
