If a+b+c>(9c)/(4) and quadratic equation ax^(2)+2bx-5c=0 has non-real roots,then-

If a + b + c >(9c)/4 and quadratic equation ax^2 + 2bx-5c = 0 has non-real roots, then-

If the equation ax^(2)+bx+c=0,0

a,b,c in R,a!=0 and the quadratic equation ax^(2)+bx+c=0 has no real roots,then

If 0

If c>0 and the equation 3ax^(2)+4bx+c=0 has no real root,then

If 0 lt a lt b lt c and the roots alpha,beta of the equation ax^2 + bx + c = 0 are non-real complex numbers, then

If 0 lt a lt b lt c and the roots alpha,beta of the equation ax^2 + bx + c = 0 are non-real complex numbers, then
