What is the difference between summing 9/10+9/100+9/1000+.... and the summation process that takes place in an integral? For example, if f(x)=1 and we compute the integral from 0 to 1, the answer is 1. One can argue that we are calculating the area of a square with side 1 unit. Is there a way to show how 0.999... ties into all of this? Evidently the integral by definition is the limit of an infinite average but 0.999... is not an average.

I'm working from a text book where the answer to (x-6)^2 = x is given as x=4 or x=9. Also where the answer to 6(x-1)^2 = 5x - 6 is given as x = 3/2 or x = 4/3. I'm not sure how to get to these answers. I know I just asked a similar question but I still need some help! :o) Thanks.

How would you factorise and solve an equation in these forms e.g (x - 2)2 = x or 6(x-1)2 = 5x - 6 or x + 4 = 36/x - 1

Really confused! Please help!
