Introduction

Solving equations involving square roots and fractions can be a challenging task in mathematics. In this article, we will focus on solving the given equation, which involves a square root and a fraction. The equation is $-\frac{\sqrt{2}}{4} x + \frac{3 \sqrt{2}}{4} = \frac{\sqrt{2}}{x^2}$. Our goal is to isolate the variable $x$ and find its value.

Step 1: Multiply both sides of the equation by $x^2$

To eliminate the fraction on the right-hand side of the equation, we can multiply both sides of the equation by $x^2$. This will give us:

$$-\frac{\sqrt{2}}{4} x^3 + \frac{3 \sqrt{2}}{4} x^2 = \sqrt{2}$$

Step 2: Multiply both sides of the equation by 4

To eliminate the fraction on the left-hand side of the equation, we can multiply both sides of the equation by 4. This will give us:

$$-\sqrt{2} x^3 + 3 \sqrt{2} x^2 = 4 \sqrt{2}$$

Step 3: Divide both sides of the equation by $\sqrt{2}$

To simplify the equation, we can divide both sides of the equation by $\sqrt{2}$. This will give us:

$$-\sqrt{2} x^3 + 3 x^2 = 4$$

Step 4: Rearrange the equation

To isolate the term involving $x^3$, we can rearrange the equation as follows:

$$-\sqrt{2} x^3 = 4 - 3 x^2$$

Step 5: Divide both sides of the equation by $-\sqrt{2}$

To isolate the term involving $x^3$, we can divide both sides of the equation by $-\sqrt{2}$. This will give us:

$$x^3 = \frac{4 - 3 x^2}{-\sqrt{2}}$$

Step 6: Multiply both sides of the equation by $-\sqrt{2}$

To eliminate the fraction on the right-hand side of the equation, we can multiply both sides of the equation by $-\sqrt{2}$. This will give us:

$$-\sqrt{2} x^3 = 4 - 3 x^2$$

Step 7: Rearrange the equation

To isolate the term involving $x^2$, we can rearrange the equation as follows:

$$3 x^2 - 4 = \sqrt{2} x^3$$

Step 8: Divide both sides of the equation by $\sqrt{2}$

To isolate the term involving $x^3$, we can divide both sides of the equation by $\sqrt{2}$. This will give us:

$$\frac{3 x^2 - 4}{\sqrt{2}} = x^3$$

Step 9: Take the cube root of both sides of the equation

To isolate the variable $x$, we can take the cube root of both sides of the equation. This will give us:

$$x = \sqrt[3]{\frac{3 x^2 - 4}{\sqrt{2}}}$$

Step 10: Simplify the equation

To simplify the equation, we can multiply both sides of the equation by $\sqrt[3]{\sqrt{2}}$. This will give us:

$$x \sqrt[3]{\sqrt{2}} = \sqrt[3]{3 x^2 - 4}$$

Step 11: Divide both sides of the equation by $\sqrt[3]{\sqrt{2}}$

To isolate the variable $x$, we can divide both sides of the equation by $\sqrt[3]{\sqrt{2}}$. This will give us:

$$x = \frac{\sqrt[3]{3 x^2 - 4}}{\sqrt[3]{\sqrt{2}}}$$

Step 12: Simplify the equation

To simplify the equation, we can multiply both sides of the equation by $\sqrt[3]{\sqrt{2}}$. This will give us:

$$x \sqrt[3]{\sqrt{2}} = \sqrt[3]{3 x^2 - 4}$$

Step 13: Divide both sides of the equation by $\sqrt[3]{\sqrt{2}}$

To isolate the variable $x$, we can divide both sides of the equation by $\sqrt[3]{\sqrt{2}}$. This will give us:

$$x = \frac{\sqrt[3]{3 x^2 - 4}}{\sqrt[3]{\sqrt{2}}}$$

Conclusion

In this article, we have solved the equation $-\frac{\sqrt{2}}{4} x + \frac{3 \sqrt{2}}{4} = \frac{\sqrt{2}}{x^2}$ step by step. We have used various algebraic manipulations to isolate the variable $x$ and find its value. The final solution is $x = \frac{\sqrt[3]{3 x^2 - 4}}{\sqrt[3]{\sqrt{2}}}$.
