Answer:

3x^2+2x−4=0

Use the quadratic formula to find the solutions

−b±√b^2−4(ac)/2a

Substitute the values

a=3, b=2, and c=−4 into the quadratic formula and solve for x.

−2±√2^2−4⋅(3⋅−4)/2⋅3

Simplify.

x = −1±√13/3

The final answer is the combination of both solutions.

x= −1−√13/3,−1+√13/3

The result can be shown in multiple forms.

Exact Form:

x= −1−√13/3,−1+√13/3

Decimal Form:

x=0.86851709…,−1.53518375…
