If (a^2+b^2)x^2+2(ac+bd)x+c^2+d^2=0 has no real root

If (a^2+b^2)x^2+2(ac+bd)x+(c^2+d^2)=0 has no real roots then

If the equation (a^2+b^2)x^2-2(ac+bd)x+(c^2+d^2)=0 has equal roots, then

Prove that the quadratic equation (a^2+b^2)x^2+2(ac+bd)x+(c^2+d^2)=0 has no real roots when ad!=bc .

If the equation (a^(2)+b^(2))x^(2)-2(ac+bd)x+c^(2)+d^(2)=0 has equal roots,then (a)ab=cd(b)ad=bc (c) ad=sqrt(bc)ab=sqrt(cd)

If the equation (a^(2)+b^(2))x^(2)-2(ac+bd)x+(c^(2)+d^(2))=0 has equal roots, then which one of the following is correct?

If the equation (a^(2)+b^(2))x^(2)-2 (ac +bd)x+c^(2)+d^(2)=0 , has equal roots , then

Prove that the equation x^2(a^2+b^2)+2x(a c+b d)+(c^2+d^2)=0 has no real root, if a d!=b c .

Prove that the equation x^2(a^2+b^2)+2x(a c+b d)+(c^2+d^2)=0 has no real root, if a d!=bc dot

IF ad ne bc then the roots of (a^2 +b^2)x^2+2x(ac+bd) +(c^2 +d^2)=0 are
