{1/(x - 1)} + {2/(x - 2)} = {3/(x - 3)} এর সমাধান-
Solution
Correct Answer: Option A
এ ধরনের অংকের ক্ষেত্রে আমরা অপশন থেকে মান নিয়ে সহজেই সমাধান করবো।
x = 3/2 হলে,
বামপক্ষ = {1/(3/2 - 1)} + {2/(3/2 - 2)}
= {1/(1/2)} + {2/(-1/2)}
= 2 - 4
= -2
ডানপক্ষ = {3/(3/2 - 3)}
= {3/(-3/2)}
= -2
সুতরাং, x = 3/2
x = 3/2 হলে,
বামপক্ষ = {1/(3/2 - 1)} + {2/(3/2 - 2)}
= {1/(1/2)} + {2/(-1/2)}
= 2 - 4
= -2
ডানপক্ষ = {3/(3/2 - 3)}
= {3/(-3/2)}
= -2
সুতরাং, x = 3/2
