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

If the roots of the quadratic equation x^(2)+px+q=0 are tan30^(@) and tan15^(@) respectively then the value of 2+q-p is

If one root of the equation x^(2)+px+q=0 is 2+sqrt(3) where p, q epsilon I and roots of the equation rx^(2)+x+q=0 are tan 268^(@) and cot 88^(@) then value of p+q+r is :
