Explanation of Solution
Given information:
The equation is given as
Formula used:
In order to find all the solutions to higher-degree equation, use synthetic division, factoring, and the
In order to Factorise the high degreepolynomial, determine all the terms that were multiplied together to get the given polynomial. Then try to factor each of the terms found in the first step. This continues until it can’t be factored anymore. When it can’t be factored further ,then polynomial is completely factored.
For an equation of the form
Calculation:
Consider the equation
This equation can be written as

In an elementary chemical reaction, single molecules of two reactants A and B form a molecule of the product C : ABC. The law of mass action states that the rate of reaction is proportional to the product of the concentrations of A and B: d[C] dt = k[A][B] (where k is a constant positive number). Thus, if the initial concentrations are [A] = = a moles/L and [B] = b moles/L we write x = [C], then we have (E): dx dt = k(ax)(b-x) 1 (a) Write the differential equation (E) with separate variables, i.e. of the form f(x)dx = g(t)dt.
