⇒ 3x – 1 = A(x – 2) (x – 3) + B(x – 1) (x – 3) + C(x – 1) (x – 2) …(1)
समी० (1) में x = 1 रखने पर,
3 – 1 = A(1 – 2) (1 – 3)
⇒ 2 = A(-1) (-2) ⇒ A = 1
पुनः समी० (1) में x = 2 रखने पर,
6 – 1 = B(2 – 1) (2 – 3)
⇒ 5 = B(1) (-1) ⇒ B = -5
समी० (1) में x = 3 रखने पर,
9 – 1 = C(3 – 1) (3 – 2)
⇒ 8 = C(2) (1) ⇒ C = 4
