To divide the polynomial
It is found that
Thus, it is found that:
Given:
The dividend:
The divisor:
Set up:
The zero of the divisor
The dividend
Calculation:
Because the leading coefficient of the dividend must be the leading coefficient of the quotient, write
Multiply the zero of the divisor,
Add the next coefficient of the dividend with the product and record the sum below the line.
Repeat the process until the end.
Interpret:
The numbers below the line give the coefficients of the quotient and the remainder.
The first four numbers (
The last number
Thus, the quotient is
Conclusion:
It is found that
Thus, it is found that:

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.
