question 238

Multiple Choice

Find the zeros and their multiplicities. Consider using Descartes' rule of signs and the upper and lower
bound theorem to limit your search for rational zeros.
- $$f ( x ) = 20 x ^ { 3 } - 47 x ^ { 2 } + 11 x + 6$$

• A) \(1 , - 3\), and \(- 2\) (each with multiplicity 1 )
• B) \(- \frac { 1 } { 4 } , \frac { 3 } { 5 }\), and 2 (each with multiplicity 1 )
• C) \(\frac { 1 } { 4 } , - \frac { 3 } { 5 }\), and \(- 2\) (each with multiplicity 1 \()\)
• D) \(- 1,3\), and 2 (each with multiplicity 1)
