campbell_st · Answer

you need to factorise the quadratics

then when you flip and multiply the 2nd fraction you'll see some common factors that can be cancelled.

anonymous · Answer

I have done that and my answer is still wrong.
((z+2)(z+10))/((z+2)(z+7))/((z^2+5z)/(z+10)(z+7))
=(z+10)^2/(z^2+5z)

campbell_st · Answer

ok... now use the fun for dividing by a fraction, flip the denominator and multiply

check your factorising
