This equation can be written as :
n² + n = 30 : n² + n - 30 = 0
This can be factored :- (n - 5)(n + 6) = 0
This gives two solutions, x = 5 [25 + 5 = 30]
and x = -6 [36 - 6 = 30]

There are two solution: -3 and +2.
There are many shell programs that will find the sum of the square of individual digits of a number. A small example is: SD=3n=2, sum=2, and SD=2.
Because an integer is a whole number and the sum of any two or more whole numbers is always a whole number.
sum of 14th square number and 10th square number
The formula for finding the nth square number is n^2. Therefore, the 3rd square number is 3^2 = 9, and the 6th square number is 6^2 = 36. To find the sum of the 3rd and 6th square numbers, you add them together: 9 + 36 = 45. So, the sum of the 3rd and 6th square numbers is 45.
