Understanding Integer Properties and Differences of Squares

The video tutorial explores a mathematical problem involving two integers, p and n, where p is greater than n and both are positive. The equation p^2 - n^2 = 12 is given, and the task is to determine possible values for p-n. The solution involves factoring the equation as a difference of squares, leading to the expression (p+n)(p-n) = 12. Various combinations of positive integers that multiply to 12 are considered, and scenarios are evaluated to find integer solutions. The conclusion is that the only possible value for p-n is 2.

What is the relationship between p and n in the given problem?

• p is greater than n

• p and n are not related

• p is equal to n

• p is less than n

What equation is given in the problem involving p and n?

• p^2 + n^2 = 12

• p + n = 12

• p^2 - n^2 = 12
