Question

Use the quadratic formula to solve the zero(s) of the quadratic equation 3x^2-4x-6=0. Round to the nearest 10th.

Answer 1

so Is because you do 3x2=6 so is

Explanation:

3x2=6

x=(o,-6) ok

is c or d

Answer 2

The zeros of the quadratic equation are (-0.9, 2.2)

Given the quadratic function: 3x² - 4x - 6 = 0

Using the quadratic formula :

• -b ± √b² - 4ac / 2a

a = 3 ; b = -4 ; c = -6

Substituting into the formula:

-(-4) ± √(-4)² - 4(3*-6) / 2(3)

4 ± √16 + 72 / 6

4 ± √88 / 6

(4 ± 9.380) / 6

(4 - 9.386) / 2 or (4 + 9.386) / 2

-0.897 or 2.231

To the nearest tenth , -0.9, 2.2
