What is the discriminant of this equation? 3x2 + 8x = 0

1 answer:

6 0

If the 2 is an exponent, it should be marked as such.
“3x2” means 3x⋅2
“3x^2” means 3x²

3x²+8x = 0
Discriminant = 8²-4(3)(0) = 64

Answer: $\frac{-1}{3}$ < n < $\frac{5}{3}$

Step-by-step explanation:

| 3n - 2 | - 2 < 1

+2 +2

| 3n - 2 | < 3

3n - 2 < 3 and 3n - 2 > -3

+2 +2 +2 +2

3n < 5 and 3n > -1

n < $\frac{5}{3}$ and n > $\frac{-1}{3}$

$\frac{-1}{3}$ < n < $\frac{5}{3}$
