$$\frac{13x^{3}-5x^{2}-4x^{4}-4x^{5}}{\left(x-1\right)\left(2x-1\right)}+\frac{5x^{2}\left(x-1\right)\left(2x-1\right)}{\left(x-1\right)\left(2x-1\right)}=-2x^{3}$$

Since \frac{13x^{3}-5x^{2}-4x^{4}-4x^{5}}{\left(x-1\right)\left(2x-1\right)} and \frac{5x^{2}\left(x-1\right)\left(2x-1\right)}{\left(x-1\right)\left(2x-1\right)} have the same denominator, add them by adding their numerators.

$$\frac{13x^{3}-5x^{2}-4x^{4}-4x^{5}+5x^{2}\left(x-1\right)\left(2x-1\right)}{\left(x-1\right)\left(2x-1\right)}=-2x^{3}$$

Do the multiplications in 13x^{3}-5x^{2}-4x^{4}-4x^{5}+5x^{2}\left(x-1\right)\left(2x-1\right).

$$\frac{13x^{3}-5x^{2}-4x^{4}-4x^{5}+10x^{4}-5x^{3}-10x^{3}+5x^{2}}{\left(x-1\right)\left(2x-1\right)}=-2x^{3}$$

Combine like terms in 13x^{3}-5x^{2}-4x^{4}-4x^{5}+10x^{4}-5x^{3}-10x^{3}+5x^{2}.

$$\frac{-2x^{3}+6x^{4}-4x^{5}}{\left(x-1\right)\left(2x-1\right)}=-2x^{3}$$

Add 2x^{3} to both sides.

$$\frac{-2x^{3}+6x^{4}-4x^{5}}{\left(x-1\right)\left(2x-1\right)}+2x^{3}=0$$

To add or subtract expressions, expand them to make their denominators the same. Multiply 2x^{3} times \frac{\left(x-1\right)\left(2x-1\right)}{\left(x-1\right)\left(2x-1\right)}.

$$\frac{-2x^{3}+6x^{4}-4x^{5}}{\left(x-1\right)\left(2x-1\right)}+\frac{2x^{3}\left(x-1\right)\left(2x-1\right)}{\left(x-1\right)\left(2x-1\right)}=0$$

Since \frac{-2x^{3}+6x^{4}-4x^{5}}{\left(x-1\right)\left(2x-1\right)} and \frac{2x^{3}\left(x-1\right)\left(2x-1\right)}{\left(x-1\right)\left(2x-1\right)} have the same denominator, add them by adding their numerators.

$$\frac{-2x^{3}+6x^{4}-4x^{5}+2x^{3}\left(x-1\right)\left(2x-1\right)}{\left(x-1\right)\left(2x-1\right)}=0$$

Do the multiplications in -2x^{3}+6x^{4}-4x^{5}+2x^{3}\left(x-1\right)\left(2x-1\right).

$$\frac{-2x^{3}+6x^{4}-4x^{5}+4x^{5}-2x^{4}-4x^{4}+2x^{3}}{\left(x-1\right)\left(2x-1\right)}=0$$

Combine like terms in -2x^{3}+6x^{4}-4x^{5}+4x^{5}-2x^{4}-4x^{4}+2x^{3}.

$$\frac{0}{\left(x-1\right)\left(2x-1\right)}=0$$

Variable x cannot be equal to any of the values \frac{1}{2},1 since division by zero is not defined. Multiply both sides of the equation by \left(x-1\right)\left(2x-1\right).

$$0=0$$

This is true for any x.

$$x\in \mathrm{R}$$

Variable x cannot be equal to any of the values \frac{1}{2},1,-4,4.

$$x\in \mathrm{R}\setminus -4,\frac{1}{2},1,4$$
