Answer:

$\frac{x - 3}{x + 4} \div \frac{x ^{2} - 1 }{ x} \\ = \frac{x - 3}{x + 4} \times \frac{x}{ {x}^{2} - 1} \\ =\frac{x(x - 3)}{(x + 4)( {x}^{2} - 1) } \\= \frac{x(x - 3)}{(x + 4)(x + 1)(x - 1)}$

Someone Explain to me how 5. Is valid ???

vichka [17]

This is valid through the law of syllogism. If you swap lines 1 and 2, then you'll have this argument:

If I step on a beehive, then I will get stung.

If I get stung by a bee, then it will hurt.

Therefore, if I step on a beehive, then it will hurt

------------------

So it's like connecting a chain together. Point A (stepping on the hive), leads to point B (getting stung), which leads to point C (getting hurt). We can take a shortcut to bypass point B to jump from A to C in one step. Check out the attached image for a visual of what I'm referring to.
