Question

The discriminant of 3.x2 - 6x + 2 = 0) is:

14

12
16

20​

Answer 1

Answer:

12

Step-by-step explanation:

we know discrimenent formula as

∴ D = b² - 4*a*c

here b = -6, a = 3 and c = 2

so we get,

∴ D = (-6)² - 4*3*2

∴ D = 36 - 24

∴ D = 12

Answer 2

Answer:

discriminant =b^2-4ac

So we have d=(-6) ^2-4×3×2

=d=36-24

=d=12

Hence, discriminant is 12
