Question

What is the remainder of (x3 – 6x – 9x + 3) ÷ (x - 3)
A. -51

B. -51
x - 3

C. -17
x

D. -17
x - 3

Answer 1

use the remainder theorem :
if f(x) divided by (x-3), then f(3) as remainder
so, what's (x^3 – 6x^2 – 9x + 3) for x=3 ? (sorry, i assumed u have typo it should -6x^2, right ?)

it is 3^3 - 6(3)^2 - 9(3) + 3 = .... ?

Answer 2

what i have there is the right one

Answer 3

try this mommy :)
3^3 - 6(3)^2 - 9(3) + 3 = ?

Answer 4

Thank for trying to help but I really do not get any of this

Answer 5

I'm doing this all online and it is very hard to try and break it down and learn how to do all this

Answer 6

well, i will figure out of it
3^3 - 6(3)^2 - 9(3) + 3
= 27 - 6(9) - 27 + 3
= 27 - 54 - 27 + 3
= -54 + 3
= - 51

Answer 7

it is A, mommy :)
