Question

Which is equivalent to 3x/x+5 - x-5/x

Answer 1

Answer:

B. $\frac{2x^2+25}{x(x+5)}$

Step-by-step explanation:

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

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

= $\frac{3x^2-(x^2-25)}{x(x+5)}$

= $\frac{2x^2+25}{x(x+5)}$

Answer 2

The answer is B - $\frac{2x^{2}+25 }{x(x+5)}$
