Ok looks like we have to do some factoring :) Hmm let's look at it piece by piece.\[\large \frac{\color{orangered}{d^29d+20}}{\color{green}{d^23d10}}+\frac{\color{royalblue}{d^22d8}}{\color{purple}{d^2+4d32}}\]Let's look at the green portion first.

We want `factors` of 10, that `add` to form 3. Hmm let's try \(10\) and \(1\). \(10\cdot1=10\) ok good, but if we try to add them, \(10+1\neq3\). Hmm ok those factors won't work. Can you think of any other factors of 10? :)

\[\frac{ (d5)(d4) }{ (d5)(d+2)}+\frac{ (d4)(d+2) }{ (d4)(d+8)}=\frac{ d4 }{ d+2}+\frac{ d+2 }{ d+8}\] i hope this helps
