Divide 8 into two parts such that the sum of their squares is 34

You can make up equations for that.

If 8 is divided into 2 parts, that means you have two factors. Let one be x and the other y.

xy = 8

Now, the sum of the square of the two factors is 34.

Hence, we have:

x^2 + y^2 = 34

Can you solve it now? :)
