n2 = n+25
n2-n-25 = 0
Using the quadratic equation formula gives n a positive value of (1+the square root of 101) over 2 which is about 5.524937811
5.5249378112 = 30.52493782 which is nearly correct.

3 squared is 9, 5 squared is 25. So the product is 225.
When the sum of a number plus 3 is squared it is 9 more than the sum of the number plus two when squared?
This is equivalent to (x + 3)2 = (x + 2)2 + 9. Multiplied out this is x2 + 6x + 9 = x2 + 4x + 4 + 9. Deduct x2 + 4x + 9 from each side giving 2x = 4 So x = 2 Check: (2 + 3) squared = 25 which is 9 more than (2 + 2) squared = 16.
