1
State the central method of Repeated Linear Factors and list the conditions that must be checked.
Faculty solution: Use including every power through the multiplicity. State the relevant hypotheses, domain or interval, units when applicable, and a verification plan.
2
Decompose 1/[x(x−1)²].
Faculty solution: 1/x−1/(x−1)+1/(x−1)².
3
Evaluate ∫1/[x(x−1)²]dx.
Faculty solution: ln|x|−ln|x−1|−1/(x−1)+C.
4
A learner makes an error by omitting required partial-fraction terms or domain-safe logarithms. Explain the first invalid step and repair the reasoning.
Faculty solution: The first invalid step is omitting required partial-fraction terms or domain-safe logarithms. Return to the governing definition or theorem, restore the missing condition, and verify the corrected result.
5
Create a short application of Repeated Linear Factors in transfer functions, rates, probability models, and rational response curves. Define variables and identify the quantity an integral, differential equation, sequence, or series would measure.
Faculty solution: A defensible response defines variables and units, states assumptions, builds the correct mathematical object, and interprets its value in transfer functions, rates, probability models, and rational response curves.
6
Describe two independent ways to verify a result from Repeated Linear Factors.
Faculty solution: Use an exact structural check such as differentiation, substitution, partial sums, or theorem hypotheses; then compare with numerical, graphical, dimensional, or limiting evidence.
