Question

to complete the square for the equation, x² + 12x - 2 = 0, you will have to add ____ to both sides. a) 6b) 12 c) 24 d) 36

Answer 1

We are given the following quadratic equation

`x^(2)+12x-2=0`

To apply the completing the square method,

We have to add the square of half the coefficient of the x -term to both sides of the equation

`((12)/(2))^2=(6)^2=36`

Therefore, we need to add 36 to both sides of the equation

Option d is the correct answer.
