Answer:
f (x) = 3(x+5) (x+2) / (x-2) (x+5)
Step-by-step explanation:
In order to make b the subject of this equation, we must isolate it on the left side. We can do this by following these steps:

Subtract b from both sides


Subtract P from both sides


Now, we have isolated b, but it is negative. We can fix this by multiplying both sides of the equation by -1.


Which is your final answer.
