Question

simplify the rational expression 5x+10/x+2 x 2x/4x-10

Answer 1

\[\frac{5x+10}{x+2} \times \frac{ 2x}{4x-10}=\frac{5(x+2)}{x+2} \times \frac{ 2x}{2(2x-5)}\]
i.e. \[5 \times \frac{ x}{(2x-5)} = \frac{5 x}{(2x-5)} \]

Answer 2

So the answer is 5x/2x-5

Answer 3

Yes

Answer 4

Thank you could you answer another for me?

Answer 5

sure

Answer 6

Simplify the rational expression 3n^2-n/n^2-1 / n^2/n+1

Answer 7

This can be expresssed as
\[\frac{3n^2-n}{n^2-1} \times \frac{ n+1} {n^2}\]
i.e.
\[\frac{n(3n-)}{(n-1)(n+1)} \times \frac{ n+1} {n^2}\]
Now cancel the like terms from the numerator as well as denominator, doing so you will get your ans

Answer 8

Is it 1/n^2?

Answer 9

Hi,are u there?

Answer 10

You should get \[3n-1divn ^{2}-n\]

Answer 11

is the answer 3n-1/n^2-n?

Answer 12

Yes! You are right! :-)
