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

a, b, c, in R, a ne 0 and the quadratic equation ax^(2) + bx + c = 0 has no real roots, then which one of the following is not true?

The quadratic equation ax^(2)+bx+c=0 has real roots if:

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

Let a,b,c in R and a gt 0 . If the quadratic equation ax^(2) +bx +c=0 has two real roots alpha and beta such that alpha gt -1 and beta gt 1 , then show that 1 + |b/a| + c/a gt 0

The quadratic equation ax^(2)+5bx+2c=0 has equal, roots if

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