Question

find the remainder when p(x)=x^3-6x^2+2x-4 when dividedby 1-2x

Answer 1

i dont remember quite well

Answer 2

what u remember tell that

Answer 3

Please reply, you need to take the initiative to reply because its ur work not mine

Answer 4

or should i tell you what is it

Answer 5

The remainder theorem is based on synthetic division, which is the process of dividing a polynomial f(x) by a polynomial D(x) and finding the remainder.

Answer 6

yes!!!

Answer 7

If p(x) is divided by x-k until a constant remainder R is obtained, then p(k)=R.
Proof:
p(x) = q(x)(x-k) + R
p(k) = q(k)(k-k) + R
p(k) = R

So -2x + 1 = 0
x = 1/2

p(1/2) = (1/2)^3 - 6(1/2)^2 +2(1/2) - 4 = -35/8 or -4.375

Answer 8

so how to solve this question b'coz the 1st polynomial of the divisor is bigger than that of the dividend . It's confusing

Answer 9

that's the remainder
-35/8 or -4.375

Answer 10

can u show it by division method

Answer 11

it would come the same wait

Answer 12

would u write the division please?

Answer 13

wait just 1 minute

Answer 14

If i do the division , it won't fit in the drawing board
@amistre64 any suggestions

Answer 15

better to walk you thru the division, instead of writing it out for you

Answer 16

what does it mean?

Answer 17

first row is the poly with all degrees filled in ....

second row is the addons starting with 0

third row is multiplication

then its just a repetitive process.

Answer 18

ms/mr no name is it so long?

Answer 19

No , it is very simple a intelligent guy like you would be able to do it easily.
To represent the division on OS is not possible. So ask your teacher on
How to do
THE LONG DIVISION OF POLYNOMIALS

Answer 20

I am not a guy.can I WRITE A PHYSICS QUESTION IN THIS REPLY BOX?

Answer 21

3 2 1 0, all degrees are present
x^3 -6x^2 +2x -4


starting with 0, we add down the columns, just focusing in the coefficients

x^3 -6x^2 +2x -4
0
----------------------
1/2 | 1

now we multiply the result by the our 1/2 and add it to the next column


x^3 -6x^2 +2x -4
0 1/2
----------------------
1/2 | 1 -11/2


and repeat till we get to the end

Answer 22

i cant understand this division it is not simple and of a high level

Answer 23

its just multiplication and addition .....

Answer 24

sorry but..........

Answer 26

thank u so much

Answer 27

Read everything don't miss out anything please

Answer 28

If you don't you are always welcome to ask :)

Answer 29

can I ask a physics question?

Answer 30

This is for a method of log division:- (Read both methods)

Answer 31

Tag me in the physics section , If i can I shall answer

Answer 32

I am new here so i don't know much about this site.

Answer 33

are u a teacher no name

Answer 34

Why ?

Answer 35

then
