9-143.

Complete the square for to determine the vertex. Then determine the

*x*‑intercepts and make a sketch of the parabola.

Completed square polynomials follow the form .

What value of

*will create*

To complete the square, let , so the completed square form would be

*.*

Where will the vertex be? Where will the

*-intercepts be?*
