Solve the equation x^2 + 5x = -1 by completing the square.

The answer to your question is: the third option

Step-by-step explanation:

              x² + 5x = - 1

              x² + 5x + = -1  +

             (x + )² =   - 1 + 25/4

            (x + )²  =  (-4 + 25) / 4

            (x + )² = 21/4

            (x + ) = ±

            x =

            x =
