If `-1, 2, alpha` are the roots of the equation `2x^3 + x^2 - 7x - 6 = 0,` then `alpha` is

If -1, 2 , alpha are roots of 2x^(3) + x^(2) - 7x - 6 = 0 then 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 the roots of the quadratic equation 2x^(2) + 3x - 7 = 0 "then" (alpha^(2) + beta^(2))/(alpha beta)=

If alpha be a root of the equation, 4 x^2 + 2x - 1 =0 , then 4 alpha^3 - 3 alpha is other root.

If alpha, beta, 1 are the roots of x ^(3) - 2x ^(2) - 7x + 6 =0, then find alpha, beta.

If alpha and beta be the roots of the equation x^(2) + 7x + 12 = 0 . Then equation whose roots are (alpha + beta)^(2) and (alpha - beta)^(2) is :

If -1,2 and alpha are the roots of 2x^3 +x^2-7x-6=0 , then find alpha

If -1,2 and alpha are the roots of 2x^3 +x^2-7x-6=0 , then find alpha
