make factors of $x^2-4$ also take 5 common in the numerator and cancel the common

So here?

$\frac{ 5x^4+10x^3 }{ 10x(x^2-4) }$ $=\frac{ 5x^3\left( x+2 \right) }{ 10x \left( x+2 \right)\left( x-2 \right) }=\frac{ x^2 } {2\left( x-2 \right) }$

7. anonymous

$x \neq0,x+2\neq0,x \neq-2$

Oh ok! I see I forgot to factor it! Thank you so much!
