$C = 0$

Step 3.10.4.1.6

Move the negative in front of the fraction.

$D = - \frac{1}{3}$

$F = \frac{1}{3}$

$G = - \frac{2}{3}$

$A = 1$

$B = 0$

$C = 0$

$D = - \frac{1}{3}$

$F = \frac{1}{3}$

$G = - \frac{2}{3}$

$A = 1$

$B = 0$

$C = 0$

$D = - \frac{1}{3}$

$F = \frac{1}{3}$

$G = - \frac{2}{3}$

$A = 1$

$B = 0$

$C = 0$

$D = - \frac{1}{3}$

$F = \frac{1}{3}$

$G = - \frac{2}{3}$

$A = 1$

$B = 0$

$C = 0$

Step 3.11

List all of the solutions.

$D = - \frac{1}{3}, F = \frac{1}{3}, G = - \frac{2}{3}, A = 1, B = 0, C = 0$

Step 4

Replace each of the partial fraction coefficients in $\frac{A}{t^{3}} + \frac{B}{t^{2}} + \frac{C}{t} + \frac{D}{t + 1} + \frac{F t + G}{t^{2} - t + 1}$ with the values found for $A$ , $B$ , $C$ , $D$ , $F$ , and $G$ .

$\frac{1}{t^{3}} + \frac{0}{t^{2}} + \frac{0}{t} + \frac{- \frac{1}{3}}{t + 1} + \frac{\frac{1}{3 t} - \frac{2}{3}}{t^{2} - t + 1}$

Step 5

Combine $\frac{1}{3}$ and $t$ .

$\frac{1}{t^{3}} + \frac{0}{t^{2}} + \frac{0}{t} + \frac{- \frac{1}{3}}{t + 1} + \frac{\frac{t}{3} - \frac{2}{3}}{t^{2} - t + 1}$
