If alpha, beta are the roots of the equation ax^(2)+bx+c=0 , find the values of the following expressions in terms of a,b,c. alpha^(4) beta^(7)+alpha^(7) beta^(4)

If alpha,beta are the roots of 1+x+x^(2)=0 then the value of alpha^(4)+beta^(4)+alpha^(-4)beta^(-4) =

If alpha and beta are the complex cube roots of 1 show that, alpha^(4)+beta^(4)+alpha^(-1).beta^(-1)=0.

If alpha, beta are the roots of 1 + x + x^(2)= 0, then the value of alpha^(4) + beta^(4) + alpha^(-4)beta^(-4) is

If 2alpha=-1-isqrt(3)and2beta=-1+isqrt(3) , then find 5alpha^(4)+5beta^(4)+7alpha^(-1)beta^(-1)

If 2alpha= -1-isqrt(3)" and"2beta= -1+isqrt(3) , then 5alpha^(4)+5beta^(4)+7alpha^(-1)beta^(-1) is equal to

If alpha , beta are the imaginary cube roots of unity then alpha^(4) + beta^(4) - (alpha + beta)^(4) =
