Step 1.1.2.1

Multiply $- 12$ by $3$ .

$y = x^{3} - 36 x^{2} + 3 x {(- 12)}^{2} + {(- 12)}^{3} - 10$

Step 1.1.2.2

Raise $- 12$ to the power of $2$ .

$y = x^{3} - 36 x^{2} + 3 x \cdot 144 + {(- 12)}^{3} - 10$

Step 1.1.2.3

Multiply $144$ by $3$ .

$y = x^{3} - 36 x^{2} + 432 x + {(- 12)}^{3} - 10$

Step 1.1.2.4

Raise $- 12$ to the power of $3$ .

$y = x^{3} - 36 x^{2} + 432 x - 1728 - 10$

Step 1.2

Subtract $10$ from $- 1728$ .

$y = x^{3} - 36 x^{2} + 432 x - 1738$

Step 2

Add $10$ to both sides of the equation.

${(x - 12)}^{3} = 10$

Step 3

Take the specified root of both sides of the equation to eliminate the exponent on the left side.

$x - 12 = \sqrt[3]{10}$

Step 4

Add $12$ to both sides of the equation.

$x = \sqrt[3]{10} + 12$

Step 5

The result can be shown in multiple forms.

Exact Form:

$x = \sqrt[3]{10} + 12$

Decimal Form:

$x = 14.15443469 \dots$
