i've been impressed by the mathematical capabilities of th pit before, so this should prove no bother for y'all.
I can't for the life of me remember how to do this:
"Express x^3  4x^2  7x +10 in its fully factorised form."
I really want to understand how to do this, aswell as get the answer, so an explanation with any answer would be much appreciated.
ecookie to whoever can help

(x+2)²(x+3)
Now go to the maths thread.
Now go to the maths thread.

Synthetic Division, cba actually doing it...

3x^2  8x  7

6x  8
Or something like that. I don't know what you mean by factorised

Why did I misread the thread title as 'Anyone fancy a carrot'?

first you have to use the maths thread.
then you have to see what could factorise by guess work (this is the way we were taught in college). First try (x1) to see if that's a factor.
f(1) = 1  4  7 + 10
it is so then you can say that (x1) is a factor
so then you divide x^3  4x^2  7x + 10 by (x1)
=> (x^34x^27x+10) = (x1)(x^2  3x  10)
=> (x1)(x5)(x+2)

That's differentiation. Whole other ballpark
