If the quadratic equation `ax^2+bx+c=0` (where a,b and c are integers) has an imaginary root `1+i`, then `3a+2b+4c=`

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

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

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

Consider a quadratic equation az^(2)bz+c=0, where a,b and c are complex numbers. The condition that the equation has one purely imaginary root , is

If a + b + c = 0 then the quadratic equation 3ax^(2) + 2bx + c = 0 has

In a quadratic equation ax^(2)+bx+c=0 if 'a' and 'c'are of opposite signs and 'b' is real, then roots of the equation are
