Quadratic !!

-1

k is negative for sure

ya rite,ans. is -1...& k has to be -ve....but how do you find out (k+p) without substituting values for k & p [7][7]

used the logic nishant bhaiyya taught me earlier....

k negative coz both roots +ve (descarte's thrm appln)

Diff of 2 odd sq = 8n

{ chk out dis link : http://targetiit.com/iit_jee_forum/posts/quadratic_2024.html }

D² - k² = -4p;

only val of p such dat 4p = 8n is 2 so u get ur p

(-3)² - 4*2 = 1²

-3 + 2 = -1......

If the roots are +ve integers and their product is p, then they have to be 1 and p.

So k = -(1+p) which means k+p = -1

YEAH PROPHET SIR!!!!

MUCH BETTER SOLN. THEN MINE COZ THER ARE A FEW ASSUMPTNS IN MY METH.....

thnx......for the soln.
