To determine which values are solutions for the quadratic equation \( x^2 + 20x = 69 \), we will rewrite the equation as:

\[ x^2 + 20x - 69 = 0 \]

Next, we will substitute each of the given values into the equation \( x^2 + 20x - 69 \) to see if the result equals zero.

  1. For \( x = -23 \): \[ (-23)^2 + 20(-23) - 69 = 529 - 460 - 69 = 0 \] This is a true statement.

  2. For \( x = 0 \): \[ (0)^2 + 20(0) - 69 = 0 + 0 - 69 = -69 \] This is not a true statement.

  3. For \( x = 12 \): \[ (12)^2 + 20(12) - 69 = 144 + 240 - 69 = 315 \] This is not a true statement.

From this analysis, we see that:

  • For \( x = -23 \), it satisfies the equation.
  • For \( x = 0 \) and \( x = 12 \), they do not satisfy the equation.

Thus, the solution set contains only the value \( -23 \).

So, the answer is: Only \( x = -23 \) is in the solution set.
