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

The roots of the equation x^(2)+px+q=0 are 1 and 2 .The roots of the equation qx^(2)-px+1=0 will be

If the roots of the equation q^2 x^2 + p^2 x + r^2 =0 are the squares of the roots of the equation qx^2 + px + r=0 , then p,q,r are in ………………….. .

If the roots of the equation qx^2 + 2px + 2q =.0 are real and unequal then prove that the roots of the equation (p + q)x^2 + 2qx + (p - q)=0 are imaginary,

If p and q are the roots of the equation x^(2)+px+q=0 , then

If , p , q are the roots of the equation x^(2)+px+q=0 , then
