If the roots of equation `ax^2 + bx + c = 0; (a, b, c in R` and `a != 0`) are non-real and `a + c > b`. Then

If the roots of the equation ax^2 + bx + c = 0, a != 0 (a, b, c are real numbers), are imaginary and a + c < b, then

If the equation ax^(2) + bx + c = 0, a,b, c, in R have non -real roots, then

If ax^2 + bx + c = 0, a, b, c in R has no real zeros, and if a + b + c + lt 0, then

The roots of the same quadratic equation ax^2 + 2bx + c = 0 (a ne 0) are real and equal then b^2 = _______

If the equaiton ax^2+bx+c=0 where a,b,c in R have non-real roots then-

If the roots of the equation ax^(2)+bx+c=0,a!=0(a,b,c are real numbers),are imaginary and a+c

If coefficients of the equation ax^2 + bx + c = 0 , a!=0 are real and roots of the equation are non-real complex and a+c < b , then

If the equation ax^2 + bx + c = 0, 0 < a < b < c, has non real complex roots z_1 and z_2 then
