Answer:

B. $\frac{6}{2x^{2} - 5x}$

Step-by-step explanation:

The product of the ratioal expressions given above can be found as follows:

$= \frac{2}{x} * \frac{3}{2x - 5}$

Multiply the denominators together, and the numerators together, separately to get a single expression

$\frac{2(3)}{x(2x - 5)}$

$= \frac{6}{x(2x) - x(5)}$

$= \frac{6}{2x^{2} - 5x}$

The product of the expression $\ = \frac{2}{x}*\frac{3}{2x - 5}$ = $\frac{6}{2x^{2} - 5x}$

The answer is B.

4 square root of 6<br> over square root of 2

NeTakaya

4 square root of 6 means 4 times $\sqrt{6}$
so the equation is $\frac{4 \sqrt{6} }{ \sqrt{2} }$
we can simplify this as a fraction
remember that $\sqrt{xy}= (\sqrt{x}) (\sqrt{y})$ so
$4 \sqrt{6}=4( \sqrt{3})( \sqrt{2})$ so it is now
$\frac{4 \sqrt{3}( \sqrt{2}) }{ \sqrt{2} }= (\frac{4 \sqrt{3}} {1} )( \frac{ \sqrt{2} }{ \sqrt{2} })= (\frac{4 \sqrt{3}} {1} )(1)=4 \sqrt{3}$
