## anonymous 3 years ago Multiply these rational expressions. Help?:

$\frac{ 5x }{ 10x+5 } \times \frac{ 4x+2 }{ 5}$

2. anonymous

5x(4x+2)/ 5(10x+5)

Sorry: I meant: $\frac{ 20x(x+2) }{ 50(x+5) }$

4. anonymous

Do I do anything further with it?

$\frac{5x}{10x + 5} \times \frac{4x + 2}{5}$ can be written as $\frac{5 (x) }{5 \left( 2x + 1 \right) } \times \frac{ 2 \left( 2x + 1 \right) }{5}$ Try to build on this.

if I am right, the answer should be $\frac{2x}{5}$

Okay, I see what I did wrong. Thank you!
