(i) ` 2P^(2)+9P+9 = 0`
(ii) `15Q^(2) + 16Q + 4 = 0`

I. p^(2) - 8p+15 = 0 II. q^(2) - 5q =- 6

I. p^(2) + 12p+35 = 0 II. 2q^(2) + 22q+56 = 0

I. p^(2)+5p+6 = 0 II. q^(2) + 3q + 2 = 0

I. 3p^(2)+10p+8 = 0 II. 2q^(2) + 3q+1 = 0

Let x^(2)-px+q=0, where p in R,q in R have the roots alpha,beta such that alpha+2 beta=0 then -(i)2p^(2)+q=0 (ii) 2q^(2)+p=0( iii) q<0 (iv) none of these

Add : 3p^(2)q^(2) - 4pq + 5, - 10p^(2) q^(2), 15 + 9pq + 7p^(2)q^(2)

I. 3p^(2) + 17p+10 = 0 II. 10q^(2) +9q+2=0

If p : x^(2) - 16 = 0, q : (x + 4)(x-4) = 0 , then p harr q
