Which constant would you add to the RIGHT side of the
quadratic equation in order to solve by completing the
square? Remember, this is a two-step process
ANSWER
The correct answer is D
EXPLANATION
The given quadratic expression is
Divide through by 3
We now add the square of half the coefficient of x because the coefficient of the quadratic term is now unity.
The constant we would add is
The correct answer is D
Answer: Option D.
Step-by-step explanation:
Given the quadratic equation , you can observe that the leading coefficient is not 1, then you have to divide both sides of the equation by 3:
Now, you can observe that the coefficient of the x-term is , so you must divide it by 2 and square it. Then you get:
Therefore, you must add to both sides of the equation.
