Which of the following is a solution of x² + 2x + 2?

To find the solutions of the quadratic equation x² + 2x + 2 = 0, we can use the quadratic formula, which is given by:

x = (-b ± √(b² – 4ac)) / 2a

In this case, the coefficients are: a = 1, b = 2, and c = 2.

First, we calculate the discriminant (b² – 4ac):

Discriminant = 2² – 4(1)(2) = 4 – 8 = -4

Since the discriminant is negative (-4), this indicates that the solutions are complex numbers. Now, we can plug the values into the quadratic formula:

x = (-2 ± √(-4)) / 2(1)

This simplifies to:

x = (-2 ± 2i) / 2

Finally, simplifying that gives:

x = -1 ± i

Thus, the solutions to the equation x² + 2x + 2 = 0 are:

x = -1 + i and x = -1 – i.
