Divisor is .

The divisor is in the form of  .

where is the root.

 

Write the terms of the dividend such that the degrees of the terms are in descending order.

 

Then write just the coefficients as shown below.

 

Write the constant of the divisor   to the left.

 

In this case, . Bring the first coefficient, , down.

 

Multiply the sum,   by  : .
