Which is the factored form of x3 - 10x2 + 27x -18 = 0?
(Points : 4)
(x + 1)(x- 3)(x -6) = 0

(x + 1)(x -2)(x + 9) = 0

(x -1)(x- 3)(x- 6) = 0

(x- 1)(x- 2)(x + 9) = 0

you missed out some signs

freckles · Answer

$$x^3 10x^2+27x18=0$$?

freckles · Answer

I don't believe the left hand side has any of the factors of the left hand side of the equations you have given as choices

anonymous · Answer

well it was what it was givin to me

freckles · Answer

no 
but it looks like x^3-10x^2+27x-18=0 was given to you

anonymous · Answer

yea

freckles · Answer

see if you can a zero
try some factors of -18 and see which gives you 0

welshfella · Answer

Hint; if one factor is (x -1) then f(1) = 0

anonymous · Answer

it would be either the first answer or last answer

freckles · Answer

if it is the first answer then you are saying -1,3,6 are the zeros
if you are saying it is the last answer then you are saying 1,2,-9 are the zeros

plug these into the initial function to see which outputs zeros for all those x's

anonymous · Answer

what numbers do I use to plug into them

anonymous · Answer

no wait it is the 3rd answer
