Step-by-step explanation:
I think your answer is 3
....
we have

Step 
Move the constants to the right side

Step 
Factor 3 out of the variable terms

Step 
Add
to both sides of the equation


Step 
Write the polynomial as a binomial squared

therefore
the answer is
Factor 3 out of the variable terms.
If you mean (3x-4)^2, the answer will be 9x^2 - 24x + 16.
