The first two steps in the derivation of the quadratic formula by completing the square are shown below.
which answer choice shows the correct next step?
step 1: ax^2+ bx+c = 0
step 2: ax^2 + bx=-c

The correct next step is the answer choice

Step-by-step explanation:

we have the quadratic equation in standard form

The steps in the derivation of the quadratic formula by completing the square are

step 1

----> given equation  

step 2

Move the constant term over to the right-hand side

step 3

The leading term is multiplied by a

so

Divide by a both sides

step 4

Multiply the linear term by 1/2

step 5

square this derived value

step 6

Add this squared value to either side of the equation

step 7

convert to the common denominator, and combine on the right-hand side

step 8

convert the left-hand side to completed-square form

step 9

take the square roots of either side

step 10

solving for the variable

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice
