Answer 1

Answer:

option c

3!!

Step-by-step explanation:

put x=-1 and equate the equation to 0

then k=3

Answer 2

$\large\underline\pink{\sf{Solution-}}$

$\large{\sf{x=-1}}$

$\large{\sf{Polynomial~-{x}^{51} + 2x {}^{49} + k -}}$

$\large{\sf{Putting~value~of~x=-1}}$

$\large\underline{\sf{So,~we~have}}$

$\large{\sf{ { - 1}^{51} + 2 \times - 1 {}^{49} + k }}$

$\large{\sf{-1~+~-2+k}}$

$\large{\sf{-3~+~k}}$

$\large{\sf{-3~+~k=0}}$

$\large{\sf{k~=~3}}$

$\large\underline\orange{\sf{Hence~value~of~k~is~3}}$

$\large\underline{\sf{Opt.c~-~3}}$
