Answer:
See below
Step-by-step explanation:

Recall

Using the chain rule

such that 
we can get a general formulation for

Considering the power rule

we have

therefore,

Now, once

we have

Hence, we showed

================================================
For the integration,

considering the previous part, we will use the identity

thus

and

Considering 
and then 
we have

Therefore,


Answer:
-6(2b-c-3)
Step-by-step explanation:
Collect like terms
-12b+6c+12+6
Add the 2 numbers on right
-12b+6c+18
Factor -6 out of expression
-6(2b-c-3)
Hopefully this helps: 16(x^2 + 6x + y^2) = 5(8y + 63)
I'm not sure where to take it from there, but hopefully someone can build off of that. :)
We need more info like a) this b) or this stuff like that
