Methods for Partial Fraction Decomposition
Partial fraction decomposition is a technique used to express a rational function as a sum of simpler fractions. There are several methods for performing partial fraction decomposition, each with its own advantages and disadvantages.
Method 1: Linear Factors
This method is used when the denominator of the rational function can be factored into linear factors. For example, consider the function:$$\fracx^2 + 2x + 1x^2
1$$
The denominator can be factored as:$$x^2
- 1 = (x
- 1)(x + 1)$$
So, we can write:$$\fracx^2 + 2x + 1x^2
- 1 = \fracAx
- 1 + \fracBx + 1$$
where A and B are constants to be determined.
Method 2: Quadratic Factors
This method is used when the denominator of the rational function can be factored into quadratic factors. For example, consider the function:$$\fracx^3 + 2x^2 + 3x + 4x^3
1$$
The denominator can be factored as:$$x^3
- 1 = (x
- 1)(x^2 + x + 1)$$
So, we can write:$$\fracx^3 + 2x^2 + 3x + 4x^3
- 1 = \fracAx + Bx
- 1 + \fracCx + Dx^2 + x + 1$$
where A, B, C, and D are constants to be determined.
Method 3: Repeated Factors
This method is used when the denominator of the rational function has repeated factors. For example, consider the function:$$\fracx^2 + 2x + 1(x
1)^2$$
The denominator can be factored as:$$(x
- 1)^2 = (x
- 1)(x
- 1)$$
So, we can write:$$\fracx^2 + 2x + 1(x
- 1)^2 = \fracAx
- 1 + \fracB(x
- 1)^2$$
where A and B are constants to be determined.
