Lutasin ang 14f(x)=x^-3+2x

$$14 f ( x ) = x ^ { - 3 } + 2 x$$

I-solve ang f

$$f=\frac{1}{7}+\frac{1}{14x^{4}}$$

$$x\neq 0$$

Mga Hakbang sa Pagso-solve ng Linear Equation

Ang equation ay nasa standard form.

$$14xf=2x+\frac{1}{x^{3}}$$

I-divide ang magkabilang dulo ng equation gamit ang 14x.

$$\frac{14xf}{14x}=\frac{2x+\frac{1}{x^{3}}}{14x}$$

Kapag na-divide gamit ang 14x, ma-a-undo ang multiplication gamit ang 14x.

$$f=\frac{2x+\frac{1}{x^{3}}}{14x}$$

I-divide ang 2x+\frac{1}{x^{3}} gamit ang 14x.

$$f=\frac{1}{7}+\frac{1}{14x^{4}}$$

I-solve ang x (complex solution)

$$x=\frac{2^{\frac{3}{4}}i\left(7f-1\right)^{-\frac{1}{4}}}{2}$$

$$x=\frac{2^{\frac{3}{4}}\left(7f-1\right)^{-\frac{1}{4}}}{2}$$

$$x=-\frac{2^{\frac{3}{4}}\left(7f-1\right)^{-\frac{1}{4}}}{2}$$

$$x=-\frac{2^{\frac{3}{4}}i\left(7f-1\right)^{-\frac{1}{4}}}{2}\text{, }f\neq \frac{1}{7}$$

I-solve ang x

$$x=\frac{2^{\frac{3}{4}}}{2\sqrt[4]{7f-1}}$$

$$x=-\frac{2^{\frac{3}{4}}}{2\sqrt[4]{7f-1}}\text{, }f>\frac{1}{7}$$
