If `z^(2)+(p+iq)z+(r+is)=0`, where,p,q,r,s are non-zero has real roots, then

For a complex number z, the equation z^(2)+(p+iq)z r+" is "=0 has a real root (where p, q, r, s are non - zero real numbers and i^(2) = -1 ), then

For a complex number z, the equation z^(2)+(p+iq)z+ r+" is "=0 has a real root (where p, q, r, s are non - zero real numbers and i^(2)-1 ), then

Find the derivative of (px + q) (r/x + s) , where p,q,r and s are non zero constants .

Find the derivative of (px + q)/(rx + s) , where p,q,r and s are non zero fixed constants .

The equation Px^(2) + qx + r = 0 (where p, q, r, all are positive ) has distinct real roots a and b .

Let z be a complex number satisfying the equation z^(2)-(3+i)z+m+2i=0, wherem in R Suppose the equation has a real root.Then root non-real root.

if the roots of the equation z^(2) + ( p +iq) z + r + is =0 are real wher p,q,r,s, in ,R , then determine s^(2) + q^(2)r .

if the roots of the equation z^(2) + ( p +iq) z + r + is =0 are real wher p,q,r,s, in ,R , then determine s^(2) + q^(2)r .
