Use the Factor Theorem to Determine Whether X - C $$f ( x ) = x ^ { 4 } + 10 x ^ { 3 } + 7 x ^ { 2 } + 61 x - 90 ; c = - 10$$

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) .
- $$f ( x ) = x ^ { 4 } + 10 x ^ { 3 } + 7 x ^ { 2 } + 61 x - 90 ; c = - 10$$

A) Yes; $f ( x ) = ( x + 10 ) \left( x ^ { 3 } + 7 x - 9 \right)$
B) Yes; $f ( x ) = ( x - 10 ) \left( x ^ { 3 } + 7 x + 9 \right)$
C) $\mathrm { No }$
D) Yes; $f ( x ) = ( x + 10 ) \left( x ^ { 3 } + x - 9 \right)$
