it says find two consecutive positive integers such that the sum of their square is 85.

how would i do this one i have no clue i know what are positive integers.but i don't know how to figure this out.

Let n be a postive integer, then n+1 is the next integer.

sum the squares of those noumbers:
n^2 + n^2 + 2n +1=85
