6-x-(9/x)=0 হলে x²÷(x²-x-3) এর মান -

B 1

C 2

D 3

Solution

Correct Answer: Option D

দেয়া আছে,
      6-x-(9/x)=0
বা,(6x-x²-9)/x=0
বা,-x²+6x-9=0
বা,-(x²-6x+9)=0
বা,x²-6x+9=0
বা,x²-2.x.3+3²=0
বা,(x-3)²=0
বা,x-3=0
অতএব,x=3

প্রদত্ত রাশি ,x²÷(x²-x-3)
                =x²/(x²-x-3)
                =3²/(3²-3-3)
                =9/(9-6)
                =9/3
                 =3
