Multiplying a decomposition through by the common denominator gives
Aa differential equation
Ba polynomial identity
Ca quadratic inequality
Da trigonometric identity
Answer & Solution
Correct answer: B. a polynomial identity
Both sides become polynomials that must agree for all x, so coefficients can be compared.
