Question:

Match the rational expression with the form of its decomposition. [The decompositions are labeled (a), (b), (c), and (d).]
(a) A/x + B / (x + 2) + C / (x - 2)
(b) A/x + B / (x - 4)
(c) A/x + B/x2 + C / (x - 4)
(d) A/x + B / (x - 4) + C / (x - 4)2
1. (3x - 1) / x (x - 4)
2. (3x - 1) / x2 (x - 4)
3. (3x - 1) / x (x - 4)2
4. (3x - 1) / x (x2 - 4)
