Find the Zeros of the Function and State the Multiplicities $$f ( x ) = [ x - ( 4 - \sqrt { 7 } ) ] [ x - ( 4 + \sqrt { 7 } ) ]$$

Multiple Choice

Find the zeros of the function and state the multiplicities.
- $$f ( x ) = [ x - ( 4 - \sqrt { 7 } ) ] [ x - ( 4 + \sqrt { 7 } ) ]$$

A) $4 \pm \sqrt { 7 }$ ; each of multiplicity 1
B) $- 4 \pm \sqrt { 7 }$ ; each of multiplicity 1
C) $4 - \sqrt { 7 } ;$ multiplicity 2
D) $4 + \sqrt { 7 }$ ; multiplicity 2
