Exercise 27 Page 113

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

2.2(x+2)

Practice makes perfect
We want to factor out the coefficient of the variable term — 2.2. Let's rewrite each term as a product of 2.2 and some other factor. To do so, note that 4.4 is 2 times 2.2. 1{2.2x &= {\color{#FD9000}{2.2}} \cdot x \\[0.5em] 4.4 &= {\color{#FD9000}{2.2}} \cdot 2 } Now we can use the Distributive Property to factor the expression. Let's go!
2.2x+4.4
