" iii) "p^(R)+3p-108

If p = -2, q = - 1 and r = 3, find the value of (i) p^(2) + q^(2) - r^(2) (ii) 2p^(2) - q^(2) + 3r^(2) (iii) p - q - r (iv) p^(3) + q^(3) + r^(3) + 3 pqr (v) 3p^(2) q + 5pq^(2) + 2 pqr (vi) p^(4) + q^(4) - r^(4)

Subtract : - 3p ^(2) + 3pq +3p x from 3p (- p -a - r)

If A = |{:(p,q,r),(r,p,q),(q,r,p):}|and A A ^(T) = I "then" p^(3) + q^(3) + r^(3) =

If zeros of the polynomial f(x)=x^3-3p x^2+q x-r are in A.P., then (a) 2p^3=p q-r (b) 2p^3=p q+r (c) p^3=p q-r (d) None of these
