If `(alpha+5i)/(2)` is a root of the equation `2x^(2)-6x+k=0` ,then the value of `k/10` is `alpha, k, in R)`

alpha&1/ alpha are roots of equation 4x^(2)-2x+k+7=0 then the value of k will be:

If alpha , beta roots of the equations x^(2) - 5x + 6 = 0 , find the value of alpha^(2) - beta^(2) .

IF alpha,beta are the roots of the equation 6x^(2)-5x+1=0 , then the value of tan^(-1)alpha+tan^(2)beta is

If one root of the equation 8x^(2)-6x-k-3=0, is the square of the other,then the values of k is

If alpha and beta are the roots of the quadratic equation x^(2)-6x+1=0, then the value of (alpha^(2))/(beta^(2))+(beta^(2))/(alpha^(2)) is

If one of the roots of the equation 2x^(2)-6x+k=0 is ((alpha+5i)/(2)), then the values of a and k are

If one root of the quadratic equation 6x^(2)-x-k=0" is" (2)/(3) , then find the value of k.
