Examples of Partial Fractions Decomposition
Let’s look at a few examples to better understand the process:
Example 1: Simple Case
Original fraction: (x + 1) / (x^2 - 1) Decomposed form: 1/(2(x-1)) + 1/(2(x+1))
Example 2: Repeated Linear Factors
Original fraction: (x + 2) / (x^2 + 2x + 1) Decomposed form: 1/(x+1) + 1/(x+1)^2
Example 3: Irreducible Quadratic Factor
Original fraction: (x^2 + x + 1) / (x^3 + 1) Decomposed form: (2x-1)/(3(x^2-x+1)) + 1/(3x)
Our calculator can handle these and even more complex cases!
