Let x and y the numbers so:
x+y=8
xy=2
y=8-x then x(8-x)=2 then -x^2+8x-2=0
x+=+%28-8+%2B-+sqrt%28+8%5E2-4%2A%28-1%29%2A%28-2%29+%29%29%2F%282%2A%28-1%29%29+ =
x+=+%28-8+%2B-+sqrt%28+56+%29%29%2F-2%29+=x+=+4+%2B-+sqrt%28+14+%29%29+
solutions are x+=+4+%2B+sqrt%28+14+%29%29+andx+=+4+-sqrt%2814%29%29
