Question

The discrimant of the quadratic equation 3 x square - 4 x-2=0 is

Answer 1

Answer:

40

Step-by-step explanation:

3x²-4x-2=0

Discriminant(D) =b²-4ac = (-4)²-4×3×(-2)=16+24= 40.

D = 40

Answer 2

Answer:

$\text{As\;you\;know,}$

$\mathsf{D= {b^2} - {4ac}}$

$\text{As\;per\;question}$

$\text{{a} = {3}}$

$\text{{b} = {-4}}$

$\text{{c} = {-2}}$

$\text{Now\;putting\;formula}$

$= \mathsf{{-4^2} - (4×3×(-2))}$

$= \text{{16} + {24} = {40}}$
