Question

When 3 x cube + X - 1 is divided by X + 1 reminder will be option A-1 option2- 2 option 3-3 option 4-4.

Answer 1

remainder will be -3

Answer 2

Answer:

-5

Step-by-step explanation:

$p(x)=3x^3+x-1$

If p(x) is divided by (x + 1), then the remainder is p(-1).

Therefore,

$p(-1)=3((-1)^3)+(-1)-1 \\ \\ p(-1)=3(-1)-1-1 \\ \\ p(-1)=-3-1-1 \\ \\ p(-1) = -5$

∴ The answer is -5.
