First Rewrite the Quadratic Function in Standard Form by Completing $f ( x ) = x ^ { 2 } + 18 x + 66 \quad$

Multiple Choice

First rewrite the quadratic function in standard form by completing the square, then find any x-intercepts and any y-intercepts.
- $f ( x ) = x ^ { 2 } + 18 x + 66 \quad$ Give your answers in exact form.

A) x-intercepts: $- 9 - \sqrt { 15 }$ and $- 9 + \sqrt { 15 } ; y$ -intercept: 66
B) x-intercepts: $- 18 - \sqrt { 66 }$ and $- 18 + \sqrt { 66 } ;$ y-intercept: $- 66$
C) x-intercepts: $9 - \sqrt { 66 }$ and $9 + \sqrt { 66 } ; y$ -intercept: 66
D) $x$ -intercepts: $9 + \sqrt { 15 } ; y$ -intercept: $- 66$
