question 99

Multiple Choice

Find the partial fraction decomposition.
- $$\frac { 3 } { x ^ { 2 } + 4 x + 3 } = \frac { A } { x + 3 } + \frac { B } { x + 1 }$$

• A) \(A = - \frac { 3 } { 2 } , B = - \frac { 3 } { 2 }\)
• B) \(A = \frac { 3 } { 2 } , B = \frac { 3 } { 2 }\)
• C) \(\mathrm { A } = \frac { 3 } { 2 } , \mathrm {~B} = - \frac { 3 } { 2 }\)
• D) \(\mathrm { A } = - \frac { 3 } { 2 } , \mathrm {~B} = \frac { 3 } { 2 }\)
