b) Factor the expression completely. (1 point)

a) Simplify the expression and explain each step:

12 + 3(2y − 3)

= 12 + 6y − 9 // distribute the 3

= 6y + 3 // combine like terms

b) Factor the expression completely:

18b − 12

= 6(3b − 2) // factor out the greatest common factor 6, then factor out 2 from 6b − 4

The completely factored form is 6(3b − 2).
