Question 934536
The product of the constant terms is {{{18}}}.
A.{{{(1)(-3)(-6)=18}}} possible choice
B.{{{(1)(-2)(9)=-18}}} not a possible choice
C.{{{(-1)(-3)(-6)=-18}}} not a possible choice
D.{{{(-1)(-2)(9)=18}}} possible choice
.
.
.
A and D remain as possible choices.
From D, {{{x=1}}} would be a zero.
Checking the original polynomial,
{{{1^3+6(1)^2-25(1)+18=0}}}
{{{1+6-25+18=0}}}
{{{25-25=0}}}
{{{0=0}}}
True, so D is the correct factored form.
