The roots of the equation `(q-r)x^2+(r-p)x+p-q=0` are (A) `(r-p)/(q-r),1` (B) `(p-q)/(q-r),1` (C) `(q-r)/(p-q),1` (D) `(r-p)/(p-q),1`

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

Prove that equations (q-r)x^(2)+(r-p)x+p-q=0 and (r-p)x^(2)+(p-q)x+q-r=0 have a common root.

Add p(p-q),q(q-r) and r(r-p)

The lines (p-q)x+(q-r)y+(r-p)=0(q-r)x+(r-p)y+(p-q)=0,(x-p)x+(p-q)y+(q-r)=

The solution of equation (p+q-x)/(r)+(q+r-x)/(p)+(r+p-x)/(q)+(3x)/(p+q+r)=0 is

If (p)/( q - r) = (p + q)/( r) = (q)/( p) , Then find q : p : r

If p,q,r epsilon R and the quadratic equation px^2+qx+r=0 has no real roots, then (A) p(p+q+r)gt0 (B) (p+q+r)gt0 (C) q(p+q+r)gt0 (D) p+q+rgt0

If p(q-r)x^(2)+q(r-p)x+r(p-q)=0 has equal roots,then prove that (2)/(q)=(1)/(p)+(1)/(r)
