7, 7, 7
Work Step by Step
Step 1: Factoring each term We want to figure out what multiplies with $2x$ to get $14x$. This is $14x/2x=7$. Similarly, what goes in the second box must multiply with 1 to get 7. Thus this value must be 7/1=7. Step 2: By the distributive law, we can factor out a 7 from each term.
