Exercise 4 Page 110

Rewrite each term as a product of the coefficient of the variable term and some other factor.

1/2( n- 1)

Practice makes perfect
We want to factor out the coefficient of the variable term — 12. Let's rewrite each term as a product of 12 and some other factor. To do so, note that any number equals itself multiplied by 1. 1/2n &= 1/2 * n 1/2 &= 1/2 * 1 Now we can use the Distributive Property to factor the expression. Let's go!
1/2n-1/2
1/2 * n-1/2
1/2 * n-1/2 * 1
1/2( n- 1)
