If `alpha, beta` are roots of the equation `ax^2 -bx - c = 0`, then `alpha^2 - alphabeta + beta^2` is equal to-

If alpha and beta are thr roots of the equation ax^(2) + bx + c = 0 then ( alpha + beta )^(2) is ……… .

If alpha, beta are the roots of the equation ax^(2)+bx+c=0 , a!=0 then alpha+beta =

If alpha and beta are the roots of equation ax^2 + bx + c = 0, then the value of alpha/beta + beta/alpha is

If alpha. beta are roots of the equation ax^(2)+bx+c=0 and alpha-beta=alpha*beta then

If alpha& beta are the roots of the equation ax^(2)+bx+c=0, then (1+alpha+alpha^(2))(1+beta+beta^(2))=

If alpha and beta are the roots of the equation ax^2+bx+c=0 where alpha 0 then (a alpha +b)(a beta +b) is equal to

If alpha,beta are the roots of the quadratic equation ax^(2)+bx+c=0 then alpha beta =

If alpha , beta are the roots of ax^2 + bx + c=0 then alpha beta ^(2) + alpha ^2 beta + alpha beta =
