1. The problem statement, all variables and given/known data

([2x+1/4x+3]^2)

2. Relevant equations
Exponent and quotient rule

3. The attempt at a solution
Would this become:

2* (2x+1/4x+3) then do the quotient rule?

Yes, but what you wrote is incorrect, due to missing parentheses. 2x + 1/4x + 3 means this:
2x + (1/4)x + 3

Do you mean (2x + 1)/(4x + 3)?
