1Statement -2 is correct...but i m not getting wat u wrote in statement -1 this thing equation p(x).q(x)...???wats the equation this is just an expression not an equation...did u mean p(x)*q(x)=0?
Statement1- if p(x)=x2+px+p1 and q(x)=x2+qx+q1 where p,p1,q,q1 are real and the equation p(x).q(x) has atmost one real root then (1+p+p1) (1+q+q1)>0
Statement2- if a quadratic ax2+bx+c has no real root then a(ax2+bx+c)>0 for all x belonging to the set of real numbers..

71He wrote equation, means of course p(x)*q(x) = 0 , else it would be an expression not equation!
