Ohh I completely forgot about a^2 - b^2 = (a+b)(a-b). Thank-you!
So (j-3)^2 - (k-5)^2 --> (j - 3 + k - 5)(j - 3 - k + 5) --> (j + k - 8)(j - k + 2) and these two are the factors!

Wow, it's amazing it's actually been done :o. I based that question off of some telegraph experiment I learned about last year, which I don't remember too clearly.
But, uh, the moon is spiraling away from the Earth..? Granted it's not a lot every year but if Earth survived long enough it's just going to spiral away?

Light bulbs emit photons and those go into my eyes so..the fact everyone in a room sees the whole room light up for an instant when the switch is flipped on and off is because light moves and bounces quickly?
