The function f (x) = (1-x) (x-3) is transformed into vertex form The answer is to change f (x) = (1-x) (x-3) into the vertex form and then (x-1) ^ 2 - 4 I've been working out - (X-2) ^ 2 + 1 for a long time. I don't know how to work out the answer

Your own calculation is correct, the answer is wrong
Do you think people who publish books now will seriously calculate the answers to all the questions? They copy them from east to west. Those experts don't have time to calculate this. Believe in yourself!
The answer to f (x) = (1 + x) (x-3) is (x-1) ^ 2 - 4
