Formula Used in “Partial Fraction Decomposition Calculator”

The standard formula for partial fraction decomposition is crucial for breaking down rational functions into simpler fractions. The general form of the partial fraction decomposition is:

For a rational function R(x) = frac{P(x)}{Q(x)}, where P(x) and Q(x) are polynomials, the expression can be decomposed as:

frac{P(x)}{Q(x)} = frac{A_1}{(x – r_1)^{n_1}} + frac{A_2}{(x – r_2)^{n_2}} + … + frac{A_k}{(x – r_k)^{n_k}} + dots + frac{B_1x + C_1}{(ax^2 + bx + c)^{m_1}} + frac{B_2x + C_2}{(ax^2 + bx + c)^{m_2}} + dots

Step-by-Step Breakdown of the Formula

  1. P(x): The numerator polynomial of the rational function.
  2. Q(x): The denominator polynomial that will be factored into linear and irreducible quadratic factors.
  3. A_i: Constants corresponding to each linear factor (i.e., roots) in the denominator.
  4. B_i and C_i: Coefficients of the linear factors in the case of irreducible quadratic expressions.
  5. n_i: The exponent of each linear factor in the decomposition.
  6. r_i: The roots of the denominator polynomial, found by factoring Q(x).
  7. m_i: The exponent fields of each irreducible quadratic factor, indicating how many times the factor appears.

Example Calculation

To illustrate how to use the formula for partial fraction decomposition, let’s consider a rational function example:

R(x) = frac{2x + 3}{(x – 1)(x + 2)}.

Input Value
Numerator (P(x)) 2x + 3
Denominator (Q(x)) (x – 1)(x + 2)
Output: A_1 A
Output: A_2 B

Using the partial fraction decomposition approach, we set up the equation:

frac{2x + 3}{(x – 1)(x + 2)} = frac{A}{x – 1} + frac{B}{x + 2}

Now, we will multiply both sides by the denominator (x – 1)(x + 2):

2x + 3 = A(x + 2) + B(x – 1)

Expanding and then combining like terms will yield values for A and B.

Solving for A and B

First, choose test values for x to get A and B.

  • For x = 1: we solve 2(1) + 3 = A(1 + 2) + B(0) => 5 = 3A => A = frac{5}{3}
  • For x = -2: we solve 2(-2) + 3 = A(0) + B(-2 – 1) => -4 + 3 = -3B => B = frac{1}{3}

Final Result

Thus, the partial fraction decomposition of our example can be presented as:

frac{2x + 3}{(x – 1)(x + 2)} = frac{5/3}{x – 1} + frac{1/3}{x + 2}
