Application +4 | -1

\alpha, \beta, \gamma, \delta

are the roots of the equation

x^4+x^3+x^2

+x+1=0

, then

\alpha^{2021}+\beta^{2021}+\gamma^{2021}+\delta^{2021}

is equal to

View answer and explanation

Correct option: B

-1

Option A (

\left(y^2+x\right)^4=C\left|\left(y^2+2 x\right)^3\right|

) is correct because it represents the general solution obtained after solving the given differential equation using appropriate substitutions and integration.
