Exercise 13 Page 120

Be careful with negatives when distributing.

1/2(q+5)

We want to factor out the coefficient of the variable term. First, we can identify the variable term in our expression. 1/2q+5/2 Notice that we have one q-term with a coefficient of 12. Let's factor out 12 from our expression!

1/2q+5/2

a * 1=a

1/2q+1* 5/2

MovePartNumRight

a* b/c=a/c* b

1/2q+1/2* 5

Factor out 1/2

1/2(q+5)

Notice that we cannot simplify our expression further.
