gahh i'll try... >_< using derivatives...

Given:

6x^2 - x + 9
x^3 + x^2 (x^2+2x + 6)

Ans.?

x^3+x^2(x^2+2x+6)(12x-1) - 6x^2-x+9 [ (x^3+x^2)(2x+2)(x^2+2x+6)(3x^2+2x) ]
[ x^3 + x^2 (x^2+2x + 6) ]^2

okei i didn't finish it. . .t0o lazy to think .. ..

oh well .. .what the heck. .i tried to use the Quotient Rule then used product rule. . i dunno if using the product rule was correct in solving x^3 + x^2 ( x^2+2x+6)... ..

i only ans. teh 1st step .. X_x

hehehehe >_<

EDIT: i dun even if what i did was right x.x

There is no answer to this you realize? if you had set it = to something it could be solved but as is the best you can do is simplify it.

Focus:
There is a banana plantation located by a desert. The plantation owner has 3000 bananas that he wants to get to the market by camel. The distance to the market is 1000 kilometers. The owner has only one camel which can carry at most 1000 bananas at any given time. The camel must eat one banana for ever kilometer it travels in order to survive. What is the largest number of bananas that can be delivered to the market?

the owner carries six bananas which he feeds to the camel in the beggining, after eating a thousand bananas the camel arrives with six bananas to spare

This problem is similar to mauz in that it has no numerical answer. It can be simplified easily by simply getting rid of the parenthesis though since they have no bearing on the problem. This allows us to simply have the 1 cancel the -1 and the rest of it turns into (a^3 + 5a^2 + 3a) or a(a^2 + 5a +3). If you don't believe let's say a = 1, we'll call your problem i and my answer ii. If a = 1 then i = 9 and ii also = 9. If a = 2 then i = 34 and ii also = 34. This will prove true for any number a.

Let's assume the owner can't carry any bananas, I'm sorry I should have mentioned that. The problem with your answer though is that you left 1994 bananas back at the plantation. I guess I should give a hint the camel cannot do the entire distance in one trip. He can't travel more than 500 kilometers and still manage to return.
