Yes i have taken this question from the site,the problem is i am not satisfied wiith the logic,thats why i wanted a different approach to tackle this question,i also pasted the solution given there but still logic is vauge.the point is i am in search of simple and clear solution.i dont think i am wrong.

comment Find the number of quadratic polynomials ax² + bx + c
Reasoning->b=a+c b ranges from 3 to 2008 x1+x2=n has n-1C1 solns.Using th elogic we get 2+3+..2007 solutions. A total of 2015027 solutions.here,condition 1 comes into picture telling us that a,b,c are distinct.Therefore the even values of b ie.4,6,8,..2008 will have one solution less ie.from the given solution subtract 1003 thus giving us 20104024.

as c=b-a when c=1 we will have 2007 pairs((2,1),(3,2)….) when c=2 we will have 2005 pairs when c-3 we will have 2004 pairs… . . . when c=2007 no. of pair is 1.
