``Every quadratic equation
`ax^(2) + bx + c = 0 ," where "a, b, c in R` has`

The roots of a quadratic equation ax^(2) + bx + c = 0 "is"

The equation 4ax^2 + 3bx + 2c = 0 where a, b, c are real and a+b+c = 0 has

Let a and b be the roots of the quadratic equation ax^(2)-bx+c=0 where a,b,c in R with discriminant c. Then the value of (4c)/(ab) is equal to

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