Column I, Column II If `a ,b ,c ,a n dd` are four zero real numbers such that `(d+a-b)^2+(d+b-c)^2=0` and he root of the equation `a(b-c)x^2+b(c-a)x=c(a-b)=0` are real and equal, then, p. `a+b+c=0` If the roots the equation `(a^2+b^2)x^2-2b(a+c)x+(b^2+c^2)=0` are real and equal, then, q. `a ,b ,ca r einAdotPdot` If the equation `a x^2+b x+c=0a n dx^3-3x^2+3x-0` have a common real root, then, r. `a ,b ,ca r einGdotPdot` Let `a ,b ,c` be positive real number such that the expression `b x^2+(sqrt((a+b)^2+b^2))x+(a+c)` is non-negative `AAx in R ,` then, s. `a ,b ,ca r einHdotPdot`
