EVIL DOCTOR:
how can u know the coordinates that crosses the x-axis as quick as possible :

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

XFlufferzX:
Y= (x-2)^3 - 6(x-2)^2 + 9(x-2)

solve for x

1) x = 2

2) -6x + 12
     x = 2

3) 9x - 18
     x = 2

wow all of 'em are 2 .___.
are my answers correct? :S

from where did yuh get this problem? is it from the past paper?
