For this case we have a factorized quadratic equation. We equal each factor to zero and thus find the roots:

Subtracting 5 from both sides we have:

Thus, the first solution of the equation is:

On the other hand we have:

Adding 3 to both sides:

Thus, the second solution of the equation is:

Answer:
The solutions of the equation are:

Answer:
Step-by-step explanation:
Hi,
for n =0, so at the beginning we have 125 individuals
for n=1 the population is decreasing by 4%
it means that we got 125 - 124*0.04 = 125*(1-0.04)=125*0.96
for n = 2 we got 
for n >= 1 we got 
so the correct answer is A
