Find the maximum/minimum value of the quadratic function x2 + 10x + 17 = y by

completing the square method.

-8

Step-by-step explanation:

y = x² + 10x + 17

Complete the square. (10/2) ² = 25

y = x² + 10x + 25 - 8

y = (x + 5) ² - 8

This is an upward parabola with a vertex at (-5, - 8). So the minimum is y = - 8.
