$\frac{x - 8}{4x {}^{2} } - \frac{5 - 12x}{6x {}^{3} } =$
​

Answer 1

Объяснение:

$\frac{x - 8}{4x {}^{2} } - \frac{5 - 12x}{6x {}^{3} } =\frac{\left(x-8\right)\times 3x}{12x^{3}}-\frac{2\left(5-12x\right)}{12x^{3}} =\frac{\left(x-8\right)\times 3x-2\left(5-12x\right)}{12x^{3}} =\frac{3x^{2}-24x-10+24x}{12x^{3}} =\frac{-10+3x^{2}}{12x^{3}}$
