Question

What is the remainder of (x^3 – 6x – 9x + 3) ÷ (x - 3)

Answer 1

is it -6x or 6x^2?

Answer 2

-6x

Answer 3

and 9x?

Answer 4

yes

Answer 5

you can find that out by either doing euclidean division of polynomials. A general way to do euclidean division of polynomials is polynomial long division. A specific (and faster) way to do it for cases where the denominator is in the form of (x-a), is to use synthetic division.

Answer 6

then eq is x^3 -15x +3 right?

Answer 7

yes

Answer 8

remainder is -15

Answer 9

Thats not an answer :/

A. -51

B. -51/x-3


C. -17 /x


D. -17 /x-3

Answer 10

the answere is -15

Answer 11

check your problem once more, is it right?? see your book

Answer 12

@jimmyao98

Answer 13

I'll take a screenshot

Answer 14

lol

Answer 15

e) none of above...

Answer 16

you can just use remainder theorem...

Answer 17

-15 maybe noanswer

Answer 18

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

= 27 - 18 - 27 + 3

= -18 + 3

= -15

Answer 19

f) teacher fail

Answer 20

computer fail*

Answer 21

g) not understanding failure of human input fail.

Answer 22

clearly supposed to be -6x^2
go point out the mistake to your teacher and tell him you deserve bonus credit.

Answer 23

tell him @Algebraic! said it was ok. He'll know what you mean.

Answer 24

h) kill teacher

Answer 25

I actually thought that it was that mistake and put in -51 and still got it wrong
