Answer:
a(a+3) are the terms which can be cancelled.
Step-by-step explanation:
In this question if we factorize both the expressions then we can get the common factors which can be cancelled.
So first we factorize a²+3a = a( a+3 )
Now the second expression 
⇒
⇒
⇒
⇒
Now it is clear to us that factors a(a+3) are the common factors that can be cancelled.
