Question

How do I find the solution to this? x2 + 2x = -2 It is a complex solution. Do I complete the square?

Answer 1

either that or use the quadratic formula (after you get that -2 to the right side by adding 2 to both sides)

Answer 2

x^2 + 2x = -2

x^2 + 2x + 2 = -2 + 2

x^2 + 2x + 2 = 0

now use the quadratic formula

Answer 3

I prefer the quadratic formula since it's more simple and direct in my opinion.
