Question

under which condition a quadratic equation ax2+bx+c=0 has no real roots​

Answer 1

Answer:

Case 1: No Real Roots

Since the quadratic formula requires taking the square root of the discriminant, a negative discriminant creates a problem because the square root of a negative number is not defined over the real line. An example of a quadratic function with no real roots is given by, f(x) = x2 − 3x + 4.

Answer 2

Answer:

Solution

Step-by-step explanation:

When a , b and c are real numbers a ≠ 0 when discriminant is negative then the roots a and b of the quadratic equation ax2+bx+c=0 are unequal and not real .
