Multiply each term within the parenthesis by color(red)(b) See full process below:

Explanation:

Multiply each term within the parenthesis by color(red)(b):

(color(red)(b) xx b^2) - (color(red)(b) xx 12b) + (color(red)(b) xx 1)

Now we can use these two rules for exponents to finalize the solution:

x^color(red)(1) = x

x^color(red)(a) xx x^color(blue)(b) = x^(color(red)(a)+color(blue)(b))

(color(red)(b^1) xx b^2) - (color(red)(b^1) xx 12b^1) + (color(red)(b^1) xx 1)

b^(1+2) - 12b^(1+1) + b^1

b^3 - 12b^2 + b
