IF `alpha` and `beta` be the roots of the equation `5x^2+7x+3=0` , find the value of `(alpha^3+beta^3)/(alpha^-1+beta^-1)`.

If alpha and beta are the roots of the equation 3x^(2)+7x+3=0 Find the value of alpha beta:

If alpha,beta are the roots of the equation x^(2)+x+1=0 , find the value of alpha^(3)-beta^(3) .

If alpha and beta are the roots of equation 2x^(2)-3x+5=0 then find the value of alpha^(2)beta+beta^(2)alpha

If alpha and beta are the roots of the equation 3x^(2) - 5x + 2 = 0 , find the value of (i) (alpha)/(beta) + (beta)/(alpha) (ii) alpha-beta (iii) (alpha^(2))/(beta) + (beta^(2))/(alpha)

If alpha and beta are the roots of the equation, 7x^2 -3x -2 = 0 , then the value of (alpha )/(1 - alpha^2) + (beta)/(1 + beta^2) is equal to :

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