A scientist is studying the population dynamics of a certain species of bacteria in a petri dish. The growth rate of the bacteria is influenced by a nutrient ‘N’ and an inhibitory substance ‘I’. The scientist develops a model to predict the bacterial population ‘P’ at time ‘t’. The model involves solving equations with ‘N’ and ‘I’ as parameters.
a. The scientist finds that the population ‘P’ at a specific time $t_0$ is governed by the equation $P^3 + NP = I$, where $N$ and $I$ are known positive constants representing nutrient level and inhibitory substance concentration, respectively. Express $N$ in terms of $P$ and $I$.
