O A. When completing the square, the equation obtained is (l)3(Simplity your answer. Use a comma to separate answers as needed.)O B.When completing the square, the equation obtained is(2

Answer 1

To find the solution of the equation,

The given equation is,

`x^2+4x=-12`

By completing square method,

`x^2+4x+4=-12+4`

we get,

`(x+2)^2=-8`

Taking square roots on both sides we get,

`(x+2)=\pm\sqrt[]{-8}`

Square root of negative number cannot be defined, Hence there is no solution.

Answer is: option: (B)

When completing the square, the equation obtained is

`(x+2)^2=-8`

There is no solution because the square root of a negative number is undefined.
