If `alpha, beta` are the roots of `px^(2) + qx + r = 0`, then `alpha^(3) + beta^(3) = "______"`.

If alpha, beta, gamma are the roots of x^(3) - px^(2) + qx - r = 0 then alpha^(3) + beta^(3) + gamma^(3) =

If alpha, beta , gamma are the roots of x^(3) - px^(2) + qx - r = 0 then alpha^(2) + beta^(2) + gamma^(2) =

If alpha, beta, gamma are the roots of x^(3) - px^(2) + qx - r = 0 then alpha^(4) + beta^(4) + gamma^(4) =

If alpha,beta,gamma are the roots of x^(3)+ px^(2)+qx + r=0, then alpha^(3) + beta^(3) + gamma^(3)=

If alpha, beta,gamma are roots of x^(3) - px^(2) + qx - r = 0 then alpha^(3) beta^(3) gamma^(3) =

If alpha,beta,gamma are the roots of x^(3)+px^(2)+qx+r=0 then alpha^(3)+beta^(3)+gamma^(3)=

If alpha, beta ,gamma are roots of x^(3) + px^(2) + qx + r = 0 then sum (1)/(alpha^(2)) =
