Answer:
1 / X² -4 = (- 1/4) / (X+2) + (1/4) / (X - 2)
Step-by-step explanation:
1 / x²-4 = 1 / (X+2) * (X-2)
1 / X²-4 = (A / X+2) + (B / X-2) = (AX - 2A + BX +2B) / X² -4
∴ 1 = (A + B) * X - 2 (A - B)
A + B = 0
- 2 (A - B) = 1
A - B = - 1/2
∴ 2A = - 1/2
A= - 1/4
B= 1/4
1 / X² -4 = (- 1/4) / (X+2) + (1/4) / (X - 2)
