Question

Answer: 2(15x+14)

Divide

30÷2=15

28÷2=14

Add 2 to the beginning

`Before: 30x+28\\After: 2(15x+14)`

Answer 2

`2 (15x + 14)`

Explanation:

To factor, you have to find what number and/or variable they both have in common. Since, only 30x has a variable the gcf will not have an x in it, only a number. The only number 30 and 28 have in common are 2. So the GCF is 2. Then, in parenthesis, you have to write the remaining of the expression:

2 (15x + 14)

To make sure you're correct, solve it an you should get 30x + 28
