Which equation has the solutions x² + 2x + 4 = 0?

To find the equation that has the solutions for x² + 2x + 4 = 0, we first need to consider what it means to solve a quadratic equation. The general form of a quadratic equation is ax² + bx + c = 0, where a, b, and c are constants.

In this case, we have:

  • a = 1
  • b = 2
  • c = 4

Next, we can apply the quadratic formula to determine the solutions:

x = (-b ± √(b² – 4ac)) / 2a

For our equation:

  • Calculate b² – 4ac:
    (2)² – 4(1)(4) = 4 – 16 = -12

Since the discriminant (-12) is negative, this tells us that the solutions will be complex (imaginary) numbers. We can simplify this further:

x = (-2 ± √(-12)) / 2(1)

This can be rewritten as:

x = (-2 ± 2i√3) / 2

So the solutions can be expressed as:

x = -1 ± i√3

In conclusion, the equation that has the solutions x² + 2x + 4 = 0 is indeed the correct quadratic equation for the given solutions, which results in complex numbers.
