Problem 166 of 7
Correct the completed-square extrema error in x^2 - 8x + 10 = (x-4)^2 + 10, so the minimum is 10.
Using a hint is okay. It just tells the trainer to give you a little more review.

1. Check the completed-square transformation.
2. Read the vertex from the corrected form.
3. Use opening direction to state the correct maximum or minimum.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
