Answer:

b is -6 or -10

Step-by-step explanation:

\frac{1}{b}  =  \frac{1}{b  - 12}  +  \frac{ {b}^{2}  + 16b + 48}{ {b}^{2}  - 12b}  \\  \\  \frac{1}{b}  =  \frac{b + ( {b}^{2}  + 16b + 48)}{b(b - 12)}  \\  \\ b   - 12= b  + ( {b}^{2}  + 16b + 48) \\  {b}^{2}  + 16b + 60= 0 \\ (b + 6)(b + 10) = 0 \\ b =  - 6 \\ and \\ b =  - 10
