Question

if the quadratic equation ax²+bx+c=0 has discriminant negetive then both roots of the equations are a real and equal b imaginary c none of these​

Answer 1

In a quadratic equation ax² + bx + c =0,

discriminant (∆) = b² - 4ac

If ∆ is negative i.e, ∆ < 0

If ∆ < 0, the roots are imaginary

∆ > 0 → Real and distinct roots

∆ = 0 → 2 equal roots

Therefore,

If discriminant is negative, roots are imaginary.

Answer 2

Answer:

b) imaginary

Step-by-step explanation:

If any quadratic equation has a negative discriminant, then it's roots are not real or imaginary.
