(k^2+7k+10)/k^2+10k+16) * (k^2+8k)/(k^2-4k-45)

I keep trying to simplify this but i cant seem to get the correct answer. Please help.
 
the answer is k/(k-9)

split all the quadratic equations...and you'll get something like this

(k+5) ( k+2) / (k + 8) ( k +2) * k ( k + 8) / (k-9) (k +5 )

all the similar items wil get canceled and you'll get

k / (k-9) which is the answer ( I think ....it is the correct answer ^^)
