the anwser would most likely be 3 because you want the LCM
Answer:

Step-by-step explanation:
we will solve this using integration by parts as the problem is a product of two functions which none of them are constants.
∫udv = uv -∫vdu ..............equ 1
∫
u=x ,
du= 1
dv =
v=∫dv= 
Substituting into equ 1
∫udv =
- ∫
<em>∫udv =
</em>
Answer:
one
Step-by-step explanation:
A negative times a negative is positive
