Methods for Solving Rational Equations

What is the purpose of partial fraction decomposition?

• To make rational functions more difficult to solve

• The purpose of partial fraction decomposition is to simplify and solve rational functions by breaking them down into simpler fractions.

• To complicate and confuse rational functions

• To add unnecessary steps to solving rational functions

What are the steps involved in solving partial fraction decomposition problems?

• Add the constants for each factor and then factor the denominator

• Divide the numerator by the denominator

• Multiply the denominator by a random number

• Identify the denominator, factor it into linear and irreducible quadratic factors, and then use the method of undetermined coefficients to find the constants for each factor.

How do you determine the unknown coefficients in partial fraction decomposition?

• By asking a friend for the coefficients

• By using a magic 8-ball

• By equating the given rational function to the sum of its partial fractions and solving for the unknown coefficients.

• By flipping a coin and guessing

How do you apply partial fraction decomposition in real-life scenarios?

• Partial fraction decomposition can be used in engineering, physics, and economics to simplify complex equations and make them easier to solve.

• Partial fraction decomposition is used in cooking to create new recipes

• Partial fraction decomposition is applied in agriculture to improve crop yield

• Partial fraction decomposition is used in fashion design to create new clothing patterns
