1. (x/3)+{4/(x+1)} = 2 হলে, x এর মান কত-
- A. 1
- B. 1
- C. 1
- D. 1
Answer: Option B
Explanation:
(x/3) + {4/(x + 1)} = 2
or, (x2 + x + 4x)/3(x + 1) = 2
or, (x2 + 5x)/(3x + 3) = 2
or, x2 + x = 6x + 6
or, x2 - 5x + 6 = 0
or, x2 - 3x - 2x + 6 = 0
or, x(x - 3) - 2(x - 3) = 0
or, (x - 2)(x - 3) = 0
∴ x = 2 or 3
