When 3 less than the square of a number n is multiplied by 2,the result is 122. if n > 0, what is the value of n?

          The value of n is:

                           n=8

Let n be a number.

Now we are given a statement that:

When 3 less than the square of a number n is multiplied by 2,the result is 122.

3 less than a square of a number n is:  n²-3.

Now when this number is multiplied by 2 we get:

2(n²-3)

Now this expression is equal to 122.

Hence,

on dividing both side by 2 we get:

( Since n=-8 is not possible as n>0 )

                      Hence, the value is:

                                 8
