Question

The discriminant of the quadratic equation 1/2x - 3x^2 + 5 = 0 is
a) 2
b) -4
c) 0
d) 4​

Answer 1

Step-by-step explanation:

1/2x - 3x^2 + 5

x - 6x^2 + 10

now, discriminant = b^2 - 4ac

here, b = -6, c = +5, a = 1

so,

(-6)^2 - 4(1)(10)

36 - 40

-4

Answer 2

Answer:

Step-by-step explanation:

1/2x - 3x^2 + 5

x - 6x^2 + 10

now, discriminant = b^2 - 4ac

here, b = -6, c = +5, a = 1

so,

(-6)^2 - 4(1)(10)

36 - 40

-4
