Question

Use synthetic division and the factor theorem to match the polynomial with its correct factor.
x^3 + x^2 + 13x +4
x^3 - x +6
x^3 + x^2 - 3x +9

Answer 1

answers
x + 4
x + 2
x+3
no factor listed for this polynomial

Answer 2

this is a lot of donkey work
you want to do it the snap way?

Answer 3

\(x^3 + x^2 + 13x +4 \) doesn't have any factors with integers

Answer 4

sorry its just that this is my last work in its like 20 questions

Answer 5

in i want to get it done so i can be over with it

Answer 6

i understand
i am just saying that this requires several steps of synthetic division, which is easy but a pain
so it is easier to factor each polynomial

Answer 7

\[x^3-x+6=(x+2) (x^2-2 x+3)\]so you see the factor right away

Answer 8

ok im lost

Answer 9

you are asked to match the polynomial with its factor

Answer 10

hold on i screwed up sorry

Answer 11

i meant since \(x^3-x+6=(x+2) (x^2-2 x+3)\) you know that \(x+2\) is a factor of \(x^3-x+6\)

Answer 12

so you can match up \(x+2\) with \(x^3-x+6\)

Answer 13

it is a weird way to ask the question

Answer 14

similarly \(x^3 + x^2 - 3x +9 =(x+3) (x^2-2 x+3)\) so you can match up \(x+3\) with \(x^3 + x^2 - 3x +9 \)

Answer 15

that is all you can do for this one

Answer 16

IN THEN x^3 + x^2 + 13x +4 FOR no factor listed for this polynomial

Answer 17

yes

Answer 18

let me make sure hold on one second

Answer 19

ok

Answer 20

here you can see for yourself that it does not factor

Answer 21

thanks

Answer 22

yw
19 to go

Answer 23

Match the polynomial with its degree or the function with its value

f(x) = x^2 - 3x + 3
g(x) = 2x^2 -1

g(3)
f(z^2)
f(4)
x^4 + 3x^2 -5x
5x^10 + 13x^4 -17x^3
g(w^3)
f(z)
5x^2 - 3x^5 -5x^3
