Question

Please help me complete the square

Answer 1

The correct answer option is a.
`(x+3)^3=12`.

Explanation:

We are given the following equation which we are to solve by completing the square method:

`x^2+6x-3=0`

Keeping the variables at one side and constant on the other side of the equation to get:

`x^2+6x=3`

Dividing the coefficient of x (6 in this case) by 2 and adding its square to both sides of the equation:

`x^2+6x+9=3+9`

`x^2+6x+9=12`

Rewriting it in the perfect square form as:

`(x+3)^3=12`
