Solution: প্রশ্নে বলা হচ্ছে যে, (t 2 - kt - 48) এর একটি উৎপাদক হচ্ছে (t - 8), তাহলে k এর মান কত ? (t - 8) যদি (t 2 - kt - 48)এর একটি উৎপাদক হয় তবে অবশ্যই (t - 8) = 0 হবে t ফলে t = 8 হয় । তাই, t = 8 এই মানটি (t 2 - kt - 48) = 0 সমীকরণে বসিয়ে পাই => 8 2 - k 8 - 48 = 0 => 64 - 48 = 8k => 8k = 16 k = 2Related questions
