2.11. Dividing a Polynomial by a Polynomial
Our final basic operation for this chapter is to divide an expression with two or more terms by another having two or more terms.
To divide one polynomial by another polynomial, follow these steps:
Write the divisor and the dividend in the order of descending powers of the variable.
Supply any missing terms, using coefficients of zero.
Set up the division in long-division form, as in the following example.
Note that this method is used only for polynomials, expressions in which the exponents are all positive integers.
Example 90:Divide (4x + x2 + 3) by (x + 1). Solution:
