Question

find the discriminant of the quadratic equation 2x-4x+3=0

Answer 1

discriminant=b²-4ac
in the equation,
a=2. b=-4. c=3

putting value,
(-4)²-4×2×3
16-24
-8

D=-8

since D<0
hence, the equation doesn't have real roots.

Answer 2

Answer:

Step-by-step explanation:

Given :-

ax² + bx + c = 0

To Find :-

Discriminant of the quadratic equation.

Solution :-

The given equation is of the form ax2 + bx + c = 0, where

a = 2,

b = – 4  

c = 3.

Therefore, the discriminant

b² – 4ac

= (– 4)2 – (4 × 2 × 3)

= 16 – 24

= – 8 < 0

Hence, the given equation has no real roots.
