Solution

Let the numbers are a and b,So according to the question,a-ba2-b2=160and a+ba2+b2=580Now this is a rtedius equation to solve so better if we use logic and then solve, So taking first equation, a-ba2-b2=160=4×40Now take a-b=4.....1and a2-b2=a-ba+b=40or 4a+b=40a+b=10....2Solving 1 and 2 we get,a=7, b=3Now check this in second equation we get, 7+372+32=580580=580So a=7, b=3.
