Complete the steps of the derivation of the quadratic formula. Step 2: Step 3: Step 4: Step 5:

Step 1
(x+b/2a)^2-[(b²-4ac)/4a^2]=0
Step 2
(x+b/2a)^2=(b²-4ac)/4a^2
Step 3
getting the square root of both sides we get
x+b/2a=√(b²-4ac)/4a^2
x+b/2a=+/-√(b²-4ac)/2a
Step 4
subtract b/2a from both sides we get:
x+b/2a-b/2a=-b/2a+/-√(b²-4ac)/2a
x=-b/2a+/-√(b²-4ac)/2a
Step 5
Simplifying the above by putting them under the same denominator we get
x=[-b+/-√(b²-4ac)]/2a
