let `alpha and beta` be the roots of ` a x^2 + bx + c` then fin the value of `1/alpha - 1/ 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 and beta are roots of ax^(2) + bx + c = 0 , then find the value of a((alpha^(2) + beta^(2))/(beta alpha)) + b((alpha)/(beta) + (beta)/(alpha))

if alpha and beta are the roots of ax^(2)+bx+c=0 then the value of {(1)/(a alpha+b)+(1)/(a beta+b)} is

I a, b and c are not all equal and alpha and beta be the roots of the equation ax^(2) + bx + c = 0 , then value of (1 + alpha + alpha^(2)) (1 + beta + beta^(2)) is

If alpha and beta are roots of the equation ax ^(2) + bx + c, then find the value of the (1)/(alpha) + (1)/(beta).

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

If alpha and beta are the roots of the equation ax^(2) + bx + c = 0 , then what is the value of the expression (alpha + 1)(beta + 1) ?
