\left(x-2\right)^{\frac{2}{3}}+\left(x-2\right)^{\frac{1}{3}}-12=0

We are given the equation:

\[
\left( x - 2 \right)^{\frac{2}{3}} + \left( x - 2 \right)^{\frac{1}{3}} - 12 = 0
\]

To solve this, let's introduce a substitution to simplify the expression. Set:

\[
y = \left( x - 2 \right)^{\frac{1}{3}}
\]

This substitution allows us to rewrite the original equation as:

\[
y^2 + y - 12 = 0
\]

Now, we can solve this quadratic equation for \( y \) using the quadratic formula:

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

For \( y^2 + y - 12 = 0 \), the coefficients are \( a = 1 \), \( b = 1 \), and \( c = -12 \). Substituting into the quadratic formula:

\[
y = \frac{-1 \pm \sqrt{1^2 - 4(1)(-12)}}{2(1)}
\]
\[
y = \frac{-1 \pm \sqrt{1 + 48}}{2}
\]
\[
y = \frac{-1 \pm \sqrt{49}}{2}
\]
\[
y = \frac{-1 \pm 7}{2}
\]

This gives two solutions for \( y \):

\[
y = \frac{-1 + 7}{2} = 3 \quad \text{or} \quad y = \frac{-1 - 7}{2} = -4
\]

Now, recall that \( y = \left( x - 2 \right)^{\frac{1}{3}} \), so we can solve for \( x \) by cubing both sides.

### Case 1: \( y = 3 \)
\[
\left( x - 2 \right)^{\frac{1}{3}} = 3
\]
Cubing both sides:
\[
x - 2 = 27
\]
\[
x = 27 + 2 = 29
\]

### Case 2: \( y = -4 \)
\[
\left( x - 2 \right)^{\frac{1}{3}} = -4
\]
Cubing both sides:
\[
x - 2 = (-4)^3 = -64
\]
\[
x = -64 + 2 = -62
\]

Thus, the solutions to the equation are:
\[
x = 29 \quad \text{or} \quad x = -62
\]
