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

37. If alpha and beta are the roots of ax^(2)+bx+c=0, then the value of (a alpha+b)^(-2)+(a beta+b)^(-2) is equal to

let alpha and beta be the roots of ax^(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,beta are the roots of ax^(2)+bx+c=0 and c!=0 .then the value of (1)/((a alpha+b)^(2))+(1)/((a beta+b)^(2)) in terms of a,b,c is

If alpha, beta are the roots of the equation ax ^(2) + bx + c =0, then the value of (1)/( a alpha + b) + (1)/( a beta + b) equals to : a) (ac)/(b) b) 1 c) (ab)/(c) d) (b)/(ac)

33. If alpha and beta are the root of ax^(2)+bx+c=0. then the value of the value of {(beta)/(a alpha+b)+(alpha)/(a beta+b)} is
