Step 1.1

Subtract $x^{2}$ from both sides of the equation.

${(y - \sqrt[3]{x^{2}})}^{2} = 1 - x^{2}$

Step 1.2

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

$y - \sqrt[3]{x^{2}} = \pm \sqrt{1 - x^{2}}$

Step 1.3

Simplify $\pm \sqrt{1 - x^{2}}$ .

Step 1.3.1

Rewrite $1$ as $1^{2}$ .

$y - \sqrt[3]{x^{2}} = \pm \sqrt{1^{2} - x^{2}}$

Step 1.3.2

Since both terms are perfect squares, factor using the difference of squares formula, $a^{2} - b^{2} = (a + b) (a - b)$ where $a = 1$ and $b = x$ .

$y - \sqrt[3]{x^{2}} = \pm \sqrt{(1 + x) (1 - x)}$

Step 1.4

The complete solution is the result of both the positive and negative portions of the solution.

Step 1.4.1

First, use the positive value of the $\pm$ to find the first solution.

$y - \sqrt[3]{x^{2}} = \sqrt{(1 + x) (1 - x)}$

Step 1.4.2

Add $\sqrt[3]{x^{2}}$ to both sides of the equation.

$y = \sqrt{(1 + x) (1 - x)} + \sqrt[3]{x^{2}}$

Step 1.4.3

Next, use the negative value of the $\pm$ to find the second solution.

$y - \sqrt[3]{x^{2}} = - \sqrt{(1 + x) (1 - x)}$

Step 1.4.4

Add $\sqrt[3]{x^{2}}$ to both sides of the equation.

$y = - \sqrt{(1 + x) (1 - x)} + \sqrt[3]{x^{2}}$

Step 1.4.5

The complete solution is the result of both the positive and negative portions of the solution.

$y = \sqrt{(1 + x) (1 - x)} + \sqrt[3]{x^{2}}$

$y = - \sqrt{(1 + x) (1 - x)} + \sqrt[3]{x^{2}}$

$y = \sqrt{(1 + x) (1 - x)} + \sqrt[3]{x^{2}}$

$y = - \sqrt{(1 + x) (1 - x)} + \sqrt[3]{x^{2}}$

$y = \sqrt{(1 + x) (1 - x)} + \sqrt[3]{x^{2}}$

$y = - \sqrt{(1 + x) (1 - x)} + \sqrt[3]{x^{2}}$

Step 2

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be $0$ or $1$ for each of its variables. In this case, the degree of the variable in the equation violates the linear equation definition, which means that the equation is not a linear equation.
