### Partial Fraction Decomposition

#### Objective:
Write out the form of the partial fraction decomposition of the function (as in [this example](#)). Do not determine the numerical values of the coefficients.

#### Problems and Solutions:

**(a)** \(\frac{x - 12}{x^2 + x - 12}\)

The partial fraction decomposition of this function is written as:
\[ \frac{A}{(x - 3)} + \frac{B}{(x + 4)} \]

This answer is marked with a green check mark, indicating that it is correct.

**(b)** \(\frac{1}{x^2 + x^4}\)

The incorrect form of the partial fraction decomposition is shown below:
\[ \frac{A}{x^2 + x} + \frac{B}{x^2 + x^2} + \frac{C}{x^2 + x^3} + \frac{D}{x^2 + x^4} \]

This answer is marked with a red cross, indicating that it is incorrect.

**Explanation of Graphs and Diagrams:**

- The diagram for problem (a) illustrates the correct partial fraction decomposition form. It consists of two terms, \(\frac{A}{(x - 3)}\) and \(\frac{B}{(x + 4)}\), merged by a plus sign.

- The diagram for problem (b) displays an incorrect attempt at partial fraction decomposition with four terms, each with denominators \(x^2 + x\), \(x^2 + x^2\), \(x^2 + x^3\), and \(x^2 + x^4\), respectively. This form is not correct for the given function.

**Note:**
Partial fraction decomposition is a technique used to break down rational functions into simpler fractions. This is commonly utilized in integration and solving differential equations.
