Given that the equation [tex]z^2+(p+iq)z+r+is=0,[/tex] where [tex]p,q,r,s[/tex] are real and non-zero root then
which one is right
1. [tex]pqr=r^2+p^2s[/tex]
2. [tex]prs=q^2+r^2p[/tex]
3. [tex]qrs=p^2+s^2q[/tex]
4. [tex]pqs=s^2+q^2r[/tex]
which one is right
1. [tex]pqr=r^2+p^2s[/tex]
2. [tex]prs=q^2+r^2p[/tex]
3. [tex]qrs=p^2+s^2q[/tex]
4. [tex]pqs=s^2+q^2r[/tex]
