First, use the FOIL method.
%28x-1%29%28x%2B6%29=x%5E2%2B6x-x-6
%28x-1%29%28x%2B6%29=x%5E2%2B5x-6
%28x-1%29%28x%2B6%29=x%5E2%2B5x-6
Then complete the square.
Don't worry about the 2 multiplier, we'll put it in later.
%28x-1%29%28x%2B6%29=x%5E2%2B5x%2B%285%2F2%29%5E2-%285%2F2%29%5E2-6
%28x-1%29%28x%2B6%29=%28x%2B5%2F2%29%5E2-%2825%2F4%29-%2824%2F4%29
%28x-1%29%28x%2B6%29=%28x%2B5%2F2%29%5E2-%2849%2F4%29
Now put it the 2.
2%28x-1%29%28x%2B6%29=2%28x%2B5%2F2%29%5E2-%2849%2F2%29
