If the quadratic equation `ax^2+bx+c=0` has `-2` as one of its roots then `ax + by + c = 0` represents

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

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

the quadratic equation 3ax^2 +2bx+c=0 has atleast one root between 0 and 1, if

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

he quadratic equation 3ax^(2)+2bx+c=0 has atleast one root between 0 and 1, if

If a+b+c=0 then the quadratic equation 3ax^2+2bx+c=0 has at least one root in

The roots of the quadratic equations ax^(2)+ bx =0 are:

If a, b, c ∈ R, a ≠ 0 and the quadratic equation ax^2 + bx + c = 0 has no real root, then show that (a + b + c) c > 0

In a quadratic equations ax^(2) + bx+ c=0 , If a=0 then it becomes:
