I'm not sure if you know this, but %28a-b%29%5E2+=+a%5E2+-+2ab+%2B+b%5E2. Therefore,
%282x-3%29%5E2
%282x%29%5E2+-+2%2A2x%2A3+%2B+3%5E2
4x%5E2+-+4x%2A3+%2B+9
4x%5E2+-+12x+%2B+9
If nobody has taught you the above formula, consider this solution instead:
%282x-3%29%5E2
%282x-3%29%282x-3%29
2x%2A2x+%2B+2x%2A-3+%2B+-3%2A2x+%2B+-3%2A-3
4x%5E2+-+6x+-+6x+%2B+9
4x%5E2+-+12x+%2B+9
