Question

if x³–3x²+4x–4 is a polynomial, then one of it's a, x–1 b, x+1 c, x–2 d, x+​

Answer 1

Answer:

i don't understand your question please explain a little bit more

Answer 2

Answer:

Step-by-step explanation:

using factor theoram if we divide f(x) then if the remainder is 0 it is a factor of f(x)

so if we take x+1

let us find the reminder if we divide f(x)with x+1

f(-1)= (-1)^3 - 3(-1)^2 +4(-1) -4

=-1-3-4-4

= -12

let us take x-1

f(1)= 1^3 - 3*1^2 +4(1)+4

=1-3+4-4

= -2

let us try

x-2

f(2)= 8 - 12 + 8 -4

=16-16

=0

so the answer is c, x-2

I used trail and error metod , remainder theoram and factor theoram as you can see
