Question

Which of the following options is not a zero of
the polynomial x3 -- 6x2 + 11x - 6​

Answer 1

Answer:

We are given the following polynomial:

p(x)=x^3-6x^2+11x-6

One of the roots of given polynomial is 3.

p(3)=(3)^3-6(3)^2+11(3)-6 = 0

We have to find the other two roots.

The polynomial can be factorized as

p(x)=x^3-6x^2+11x-6

g(x) = \dfrac{x^3-6x^2+11x-6}{x-3}

g(x) = x^2-3x +2

g(x) = 0

x^2-3x +2= 0

 x^2 - x -2x + 2 =0

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

 (x-1)(x-2) = 0

x = 1, x = 2
