Question

What is the difference? X-8/3x - 3x/x^2

Answer 1

Answer:

$\frac{x - 8}{3x} - \frac{3x}{ {x}^{2} } \\ \\ \frac{x - 8}{3x} - \frac{3}{x} \\ \\ \frac{x - 8 - 9}{3} \\ \\ \frac{ x - 17}{3x}$

Answer 2

Answer:

$\\ \frac{x - 8}{3x} - \frac{3x}{ {x}^{2} }$

$\\ = \frac{x - 8}{3x} - \frac{3 {\cancel{x}}}{{ \cancel {x^2} }}$

$\\ = \frac{x - 8}{3x} - \frac{3}{x}$

$\\ = \frac{x - 8 - 9}{3}$

$\\ = \frac{x - 17}{3x}$
