Let's solve the quadratic equation:

\[
3x^2 - 4x = 4
\]

### Step 1: Bring all terms to one side of the equation.
Subtract 4 from both sides:

\[
3x^2 - 4x - 4 = 0
\]

### Step 2: Apply the quadratic formula.
The quadratic formula is:

\[
x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
\]

For the equation \(3x^2 - 4x - 4 = 0\), we have:
- \(a = 3\)
- \(b = -4\)
- \(c = -4\)

### Step 3: Plug in the values.
First, calculate the discriminant:

\[
\Delta = b^2 - 4ac = (-4)^2 - 4(3)(-4) = 16 + 48 = 64
\]

Now, solve for \(x\):

\[
x = \frac{-(-4) \pm \sqrt{64}}{2(3)} = \frac{4 \pm 8}{6}
\]

### Step 4: Find the two solutions.
- For \(x_1\):

\[
x_1 = \frac{4 + 8}{6} = \frac{12}{6} = 2
\]

- For \(x_2\):

\[
x_2 = \frac{4 - 8}{6} = \frac{-4}{6} = -\frac{2}{3}
\]

### Final solutions:
The solutions are:

\[
x_1 = 2, \quad x_2 = -\frac{2}{3}
\]
