Awarding branliest for first correct answer

Step-by-step explanation:

x² - y² =  (x + y)(x-y)

c² - (5b - 3a)² = (c + [5b -3a]) ( c - [5b - 3s] )

                     = (c + 5b - 3a) (c - 5b + 3s)

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
