Use the formula (n2 + 7) - n2 = 7, expand the equation to get
n2 + 7n + 7n + 49 - n2 = 7, eliminate what you can to get 14n + 49 = 7, then isolate 'n' by subtracting 49 from both sides of the equation which will now be 14n = -42, now you divide both sides of the equation by 14 to get n = -3.
Since 'n' is squared, you know that the two possible combinations of numbers can be either positive or negative. Their equation will look like this;
16 - 9 = 7, or 42 - 32 = 7, or (-42) - (-32) = 7.
when you subtract one square number with another the answer is 16 what are the two numbers
4 and 9
16 and 4
5 and 2
1 and 36
9 and 25
1 and 4?
That isn't possible.
4 and 3
25 and 4 or 121 and 100
The square numbers are: 16-4 = 12
16 and 25
