If the roots of equation `x^2 + qx + p = 0` are cach I less than the root of the equationsis equation `x^2 + px +q=0,` then `(p+q)` is equal to

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

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