Question

examine whether x - 1 is a factor of the following polynomial x3 - 3x2 - 9x +5​

Answer 1

Answer:

No

Step-by-step explanation:

The zero of the polynomial is x=1.

So,

f(x)=x3-3x2-9x+5

=)f(1)= 1-3-9+5

=)f(1)=6-12

=)f(1)= -6

Since th remainder is -6,

x-1 is not a factor of x3-3x2-9x+5.
