Note that the formula is: ax² + b(x) + c =0

You are trying to write it in the form: a(x - b)² = c


Note that:

a = 6

b = 12

c = 9


Plug into corresponding places: 6(x - 12)² = 9


Because you are just telling us to write it in the form a(x − b)² = c, 6(x - 12)² = 9

is your answer




hope this helps
