I got 40x(x+2) simply by multiplying the denominators. This trick only works if the GCF between each pair is 1.

after all of that cancellation, you are left with 40*(x+2) + 40x = x*(x+2)*9

so its 8?
jim_thompson5910
  • jim_thompson5910
yep x = 8 and x+2 = 10 are your two integers
jim_thompson5910
  • jim_thompson5910
you'll find that 1/8 + 1/10 = 9/40
