Is this project still ongoing? If it is, I'll sign up as a tutor.

I need someone to explain this simply.
Zeno states that for motion to occur, an object must change the position which it occupies. He gives an example of an arrow in flight. He states that in any one (durationless) instant of time, the arrow is neither moving to where it is, nor to where it is not.[11] It cannot move to where it is not, because no time elapses for it to move there; it cannot move to where it is, because it is already there. In other words, at every instant of time there is no motion occurring. If everything is motionless at every instant, and time is entirely composed of instants, then motion is impossible.
How can I factorize an equation like 3xy-1-3x+y?
Also, if someone could do (x²-x-2)/(x-2) and leave their traces. Thanks.

For 3xy-1-3x+y, you factorise it by grouping, where you group the terms into two separate groups, and then factorise accordingly.
So it will becomes something like this: 3xy-1-3x+y = 3xy-3x+y-1 = 3x(y-1)+1(y-1) =(3x+1)(y-1)
For (x^2-x-2)/(x-2), you need the factorise the numerator first. Then you will be able to cancel off the like terms.
So it will become something like this: (x^2-x-2)/(x-2) = (x+1)(x-2)/(x-2) = (x+1)
I'm not really sure how to explain the grouping part without confusing you, so I'd leave it to someone else to do it. :x
Also, can anyone explain the formation of meanders, slip off slopes and river cliffs for me? It'd be great if you used inner/outer banks instead of concave and convex banks for the formation of meander!
Were you aware about that you replied to a two years old post?
