If sum of roots is equal to sum of their reciprocals for the equation `x^(2)-px+q=0,|q|!=1`, then the value of `(p-q^2-1)/(q^2+1)`

If 2+sqrt(3)i is a root of the equation x^(2)+px+1=0, then write the values of p and q.

If one root is square of the other root of the equation x^(2)+px+q=0, then the relation between p and q is p^(3)-q(3p-1)+q^(2)=0p^(3)-q(3p+1)+q^(2)=0p^(3)+q(3p-1)+q^(2)=0p^(3)+q(3p+1)+q^(2)=0

If p and q are the roots of the quadratic equation x^(2)+px-q=0 , then find the values of p and q.

If p, q are the roots of equation x^(2)+px+q=0, then value of p must be equal to

If the roots of the equation x^2 + px-q = 0 are tan 30^@and tan 15^@ then the value of 2-q-p is
