Answer:
The factors are 1, 2, and 3
Step-by-step explanation:
According to Factor theorem, if (x - a) is a polynomial factor f(x), then f(a) = 0
let f(x)=x3-6x2+11x-6
Let us check if (x - 1) is the factor of f(x),
Then,
f(1)=13-6(12)+11(1)-6=1-6=1-6+11-6=0
Therefore (x-1) is a factor of f(x)
Let us check for the other factors
Hence,
f(x) =(x - 1) (x2 - 5x+6)
x2-5x+6=x2-2x-3x+6
=x(x - 2) -3(x - 2)
=(x - 2) (x - 3)
f(x) =(x - 1) (x - 2) (x - 3)
Therefore, 1, 2, 3 are the factors of f(x)
