Suppose the numbers are x and y.Then (x - y)^2 = x^2 - 2xy + y^2 = x^2 + y^2 - 2xy
That is 8^2 = x^2 + y^2 - 2*17
64 = x^2 + y^2 - 34
So x^2 + y^2 = 64 + 34 = 98.
No - the product of numbers is the answer to a multiplication sum, while the sum of numbers is the answer to an addition sum.
The difference of two squares is equivalent to the sum, times the difference, of the numbers that are squared. In symbols: a2 - b2 = (a + b)(a - b) Here is an example with numbers: 102 - 92 = (10+9)(10-9)

xy=24 (x^2)+(y^2)=73
The sum is the total when numbers are added together, the product is the total when they are multiplied.

The difference.
The sum of the squares of the first 100 natural numbers [1..100] is 338350, while the sum of the first 100 natural numbers squared is 25502500.

six, nine 9 + 6 = 15 (sum) 9 - 6 = 3 (difference) 9 x 6 = 54 (product)
six, seven 7 + 6 = 13 (sum) 7 - 6 = 1 (difference) 7 x 6 = 42 (product)
The numbers are zero and 5. Their product is zero.
The numbers are 13 and 8 The product is 104
The sum of their squares is 10.
