Use the Factor Theorem to Determine Whether X - C $$f ( x ) = x ^ { 6 } - 12 x ^ { 4 } - 69 x ^ { 2 } + 80 ; c = 4$$

Multiple Choice

Use the Factor Theorem to determine whether x - c is a factor of f. If it is, write f in factored form, that is, write f in the
form f(x) = (x - c) (quotient) .
- $$f ( x ) = x ^ { 6 } - 12 x ^ { 4 } - 69 x ^ { 2 } + 80 ; c = 4$$

A) Yes; $f ( x ) = ( x - 4 ) \left( x ^ { 5 } - 5 x ^ { 4 } + 5 x ^ { 3 } + 16 x ^ { 2 } - 5 x - 20 \right)$
B) No
C) Yes; $f ( x ) = ( x - 4 ) \left( x ^ { 5 } + 4 x ^ { 4 } - 4 x ^ { 3 } + 20 x ^ { 2 } - 5 x - 20 \right)$
D) Yes; $f ( x ) = ( x - 4 ) \left( x ^ { 5 } + 4 x ^ { 4 } + 4 x ^ { 3 } + 16 x ^ { 2 } - 5 x - 20 \right)$
