Question

The discriminant of the quadratic equation. 2 X ² - 4 X + 3 = 0 is
a ). 8
b ) - 8
c ) 4
​

Answer 1

Answer:

D = b²-4ac

Here a = 2, b = -4 and c = 3

D = (-4)² - 4 × 2 × 3

D = 16 - 24

D = -8

Answer 2

Step-by-step explanation:

2x

2

−6x+3=0

Here a=2,b=−6,c=3

As we know that,

Discriminant (D)=b

2

−4ac

∴D=(−6)

2

−4×2×3

⇒D=36−24=12>0

Thus, the roots are real and different.
