Step 1:
I'll solve this step by step, carefully following the LaTeX formatting guidelines:

Step 2:
: Expand the first term 3(x- 2)^{2}

- Multiply by $$3$$: $$3(x-2)^{2} = 3x^{2} - 12x + 12
- First, expand (x- 2)^{2} using the square of a binomial formula: a^{2} = a \cdot a

Step 3:
: Expand the second term - 2(x- 1)

- Distribute $$-2$$ to $$(x-1)
- - 2(x- 1) = - 2x + 2

Step 4:
: Combine the expanded terms

- $$= 3x^{2} - 12x + 12 - 2x + 2
- Add the results from Step 1 and Step 2

Step 5:
: Simplify by combining like terms

- Combine the linear terms: $$-12x - 2x = -14x
- Combine the constant terms: 12 + 2 = 14

Final Answer

3x^{2} - 14x + 14
