3.1 Partial Fractions:

A fraction of the form

1 73
3 2 x x where the degree of the numerator is less than the degree of the denominator is referred to as a proper fraction. If the degree of the numerator is greater than or equal to the degree of the denominator the fraction is referred to as an improper fraction.

An improper fraction of the form

1 1 2 2 x x may be written as 1 211
2 1 1 1 1 222
2 2 2 xxx x x x This process is called expressing or decomposing a single fraction as a sum of two (or several) separate fractions or Partial fractions.

Example1

Consider the rational expression

11 2 2x x x This expression can be expressed in the compact form as 11 112
2 2 xx xxx 11 23
2 2 xx xx

Example 2

Consider the expression

42
3 xx x This expression can be expressed as the sum of two Partial fractions as 42
3 xx x 42x
B x A Here the values of A and B are to be determined in the following way, 42
3 xx x 42x
B x A
