## How do you solve a system of equations with partial fractions?

If there are factors that look like (ax2 + bx + c)u, setup partial fractions like this: Clear fractions by multiplying each side of the equation by the denominator of the left side. Choose values of x that will cancel out terms to solve your constants A, B, C, etc. Substitute in and solve for the constants in you can.

## What is the method of partial fractions?

The method of partial fractions is a technique of algebra. It allows you to re-write complicated. fractions using simpler pieces. Recall that a rational function is a function f(x) = P(x)

**What are the 4 cases of partial fraction decomposition?**

Special Cases of Partial Fraction Expansion

- Order of numerator polynomial is not less than that of the denominator.
- Distinct Real Roots.
- Repeated Real Roots.
- Complex roots.
- An exponential (or other function) in the numerator.

**Why do we use partial fractions?**

Partial Fractions are used to decompose a complex rational expression into two or more simpler fractions. Generally, fractions with algebraic expressions are difficult to solve and hence we use the concepts of partial fractions to split the fractions into numerous subfractions.

### What is the first step in performing partial fraction expansion?

What is the first step in performing partial fraction expansion? Factor the numerator as completely as possible. Factor the denominator as completely as possible.

### Who discovered partial fractions?

The concept was discovered independently in 1702 by both Johann Bernoulli and Gottfried Leibniz.

**Why are partial fractions important?**

The importance of the partial fraction decomposition lies in the fact that it provides algorithms for various computations with rational functions, including the explicit computation of antiderivatives, Taylor series expansions, inverse Z-transforms, and inverse Laplace transforms.
