Question

if x³-3x²-9x+6 is divided by (x-3) , then the remainder is​

Answer 1

Answer:

reminder is 21

Step-by-step explanation:

Given polynomial p(x)=x³-3x²-9x +6

Given divisor=x-3

As we know remainder theorem

if p(x) is divided by (x-a) then the remainder is p(a)

now given p(x) is divided by (x-3) then the remainder is p(3)

=>p(3)=3³-3(3)²-9(3)+6

=>27-27-27+6

=>0-27+6

=>-27+6

=>-21

Answer 2

Answer:

Here is your answer

Step-by-step explanation:

Given

P(x) = x^3 - 3x^2 - 9x + 6

Factor = (x - 3)

Solution

P(3) = 27 - 27 - 27 + 6

P(3) = -21

Hence the remainder is -21
