Question

I PUUL UNUI
a quadratic equation ax2 + bx + c = 0 has
) two distinct real roots, if 62 - 4ac.> 0,
two equal real roots, if b2 - 4ac = 0,
no real roots, if b2 - 4ac < 0.
Let us consider some examples.
mple 16: Find the discriminant of the quadratic equa
e find the nature of its roots.
tion : The given equation is of the form ax2 + bx+c=
- Therefore, the discriminant
b2 - 4ac = (-4)2 – (4 x 2 x 3) = 16 - 24​

Answer 1

Answer:

No real roots exist

Step-by-step explanation:

Since your discriminant is < 0, the given equation has no real roots.

Answer 2

Answer:

no real roots

Step-by-step explanation:

b2-4ac=16-24

= -8

b2-4ac<0

:. equation has no real roots
