Partial Fraction Decomposition Concepts

What is the primary goal of partial fraction decomposition in calculus?

• To find the roots of polynomial equations.

• To solve quadratic equations.

• To simplify complex rational functions for easier integration.

• To combine multiple rational expressions into one.

When performing partial fraction decomposition, what should you do if the degree of the numerator is greater than the degree of the denominator?

• Subtract the denominator from the numerator.

• Divide the denominator into the numerator to obtain a polynomial.

• Add a constant to the numerator.

• Multiply the numerator by the denominator.

In the process of partial fraction decomposition, what form should the numerator take if the denominator has a quadratic factor?

• A cubic expression.

• A quadratic expression.

• A linear expression Bx + C.

• A constant.

What is the first step in solving the basic equation in partial fraction decomposition?

• Add all terms together.

• Select values of X to simplify the equation.

• Subtract the smallest term from the largest.

• Multiply by the least common denominator.

In the example with distinct linear factors, what value of B was determined?

• 1/5

• 1/4

• 1/3

• 1/2

How do you handle repeated linear factors in partial fraction decomposition?

• Multiply all terms by the repeated factor.

• Ignore the repeated factors.

• Include additional fractions for each repetition.

• Divide the repeated factor by the numerator.

In the example with repeated linear factors, what was the value of C?

• 0

• 1

• -1

• 2

What is the final step in partial fraction decomposition after determining the values of A, B, and C?

• Combine all fractions into one.

• Rewrite the original expression using the determined values.

• Add a constant to each fraction.

• Multiply all terms by the least common denominator.

What is the purpose of selecting the zeros of linear factors when solving the basic equation?

• To make the equation more complex.

• To simplify the process of finding unknowns.

• To eliminate the need for a common denominator.

• To increase the degree of the equation.
