To determine which values of \( x \) are solutions to the equation \( x^2 + 20x = 69 \), we will first rewrite the equation in standard form:
\[ x^2 + 20x - 69 = 0 \]
Next, we will substitute each given \( x \) value into the equation and evaluate it to check if it equals zero.
-
For \( x = -23 \): \[ (-23)^2 + 20(-23) - 69 = 529 - 460 - 69 = 0 \] True statement: Yes, \( -23 \) is a solution.
-
For \( x = 0 \): \[ (0)^2 + 20(0) - 69 = 0 + 0 - 69 = -69 \] True statement: No, \( 0 \) is not a solution.
-
For \( x = 12 \): \[ (12)^2 + 20(12) - 69 = 144 + 240 - 69 = 315 \] True statement: No, \( 12 \) is not a solution.
Now we summarize the results in the table:
| x | Substituted | Evaluate | True Statement? | |-------|---------------------------|-----------|---------------------------| | -23 | \((-23)^2 + 20(-23) - 69\) | 0 | Yes | | 0 | \(0^2 + 20(0) - 69\) | -69 | No | | 12 | \(12^2 + 20(12) - 69\) | 315 | No |
The only value from the given set that is in the solution set is:
Only \( x = -23 \) is in the solution set.
