Factor x3 4x2 3x + 18 = 0, given that 3 is a zero.

4 answers

check your typing.
Did you forget any + or - signs between the first 3 terms ?

The way it reads makes no sense.
oh sorry x3-4x2-3x+18=0
Use the ^ sign to indicate exponents

x^3 - 4x^2 - 3x + 18 = 0
since 3 is a root,
then x = 3 , or x-3 is a factor

using either long division or synthetic division,
x^3 - 4x^2 - 3x + 18
(x-3)(x^2 - x - 6) = 0
(x-3)(x-3)(x+2) = 0
so x = 3 or x = -2
thank you this make way more since now
