Question

use the remainder theorem to find the remainder whewn 2x^3-x^2-3x+7 is divided by x+2. state whether the binomial is a factor of the polynomial
a. 25;yes
b. -7;no
c. 33;no
d. -11;yes

Answer 1

the remainder will be the value of f(2)

Answer 2

Actually f(-2)

Answer 3

i know but its not the answer tho

Answer 4

yes sorry f(-2)

Answer 5

it does come to one of the options

Answer 6

c? d?

Answer 7

you are guessing

Answer 8

well 33 divide by 3 is 11

Answer 9

Answer 11

not -19

Answer 12

Oops sign mistake!

Answer 13

=-7 lol

Answer 14

-7

Answer 15

thanks guys

Answer 16

b.

\[\frac{2 x^3-x^2-3 x+7}{x+2}=\left(2 x^2-5 x+7\right)-\frac{7}{x+2} \]

Answer 17

Remainder theorem states that the remainder when the polynomial P(x) is divided by ( x -a) the remainder is f(a)
