The roots of the equation `(q-r)x^2+(r-p)x+(p-q)=0`

If rational numbers a,b,c be th pth, qth, rth terms respectively of an A.P. then roots of the equation a(q-r)x^2+b(r-p)x+c(p-q)=0 are necessarily (A) imaginary (B) rational (C) irrational (D) real and equal

If p,q are real p!=q, then show that the roots of the equation (p-q)x^(2)+5(p+q)x-2(p-q)=0 are real and unequal.

If p, q, r are real and p ne q , then the roots of the equation (p-q)x^(2) +5(p+q) x-2(p-q) r are

The roots of the equation (x-p) (x-q)=r^(2) where p,q , r are real , are

If the roots of the equation x^(2)+(p+1)x+2q-q^(2)+3=0 are real and unequal AA p in R then find the minimum integral value of (q^(2)-2q)

If the roots of the equation qx^(2)+2px+2q=0 are roots of the equation (p+q)x^(2)+2qx+(p-q) are imaginary
