If tan `25^(@) and tan 20^(@)` are roots of the quadratic equation `x^(2) + 2px + q = 0`, then 2p - q is equal to

If tan A and tan B are the roots of the quadratic equation x^(2)-px+q=0 then value of sin^(2)(A+B)

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 the roots of equation x^(2)+qx+p=0 are cach I less than the root of the equationsis equation x^(2)+px+q=0, then (p+q) is equal to

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